Otherwise, if the light energy is not handled properly by the leaf, significant damage may be induced to the plant itself. Importance of Photosynthesis. It is a series of complex biochemical reactions and occurs in higher plants, algae, some bacteria and some photoautotrophs. However, animals including human beings cannot synthesize their own food. Hence, we may summarize the overall reaction of Stage 1 and Stage 2 as follows: In this step of photosynthesis, energy depleted compounds ADP and NADP+ are converted to high energy forms. Photosynthesis is the process which maintains the balance of gases in the atmosphere. Carbon dioxide and … Columbia University: The Carbon Cycle and Earth's Climate, Georgia Tech: Making the Oxygen We Breathe, a Photosynthesis Mechanism Exposed, State University of New York Cortland: Non-Photosynthetic Plants, California State University, Sacramento: Kingdom Fungi. There is an inter membrane space between the two membranes, in addition. Structurally, the chloroplasts are double membraned cell organelle. Photosynthesis and Respiration. Download Entri App! The Relationship Between Photosynthesis Cellular Respiration. Photosynthesis provides the basic energy source for virtually all organisms. It contributes to the carbon cycle between the earth, the oceans, plants and animals. Importance Of Photosynthesis; Importance Of Photosynthesis. In step one, the cytoplasm of the cell breaks down glucose in a process called glycolysis, producing two pyruvate molecules from one glucose molecule and releasing a bit of ATP. Photosynthesis takes place in the green leaves of the plants. They use raw materials like sunlight, water and carbon dioxide to prepare the food by a process called photosynthesis. In this process, the conversion of solar energy to chemical energy takes place. What would happen if we didn’t have it? Usually NADP+ is the electron acceptor. This is your chance to win amazing discounts! They are usually found in the guard cells of the leaves. Moreover, both a and b reflect the green light. Photosynthesis occurs in chloroplasts. Additionally, the Glucose fuels various cellular activities. Photosynthesis And Cellular Respiration By Hayley Schenk On Prezi Next. Apart from this, all living things breathe in oxygen. Without photosynthesis there would be little to no oxygen on the planet. This is true to all the animals including heterotrophs … Photosynthesis occurs primarily in the leaves of the plants, which contain the highest concentration of chloroplasts. Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. Nevertheless, all the processes take place in the chloroplast itself. Furthermore, we shall represent this reaction by an equation as given below: Apart from the chlorophyll pigment, plants also possess carotenoids. And this process releases energy . For the most part, the planet’s living systems are powered by this process. Furthermore, the proton gradient is essential for ATP production. Here, carbohydrates is synthesized by the energy from the light phase (ATP and NADPH) . The Indian pipe plant is a ghostly white color because it contains no chlorophyll. Secondly, we will acquire an awareness on the importance of photosynthesis. All living beings require food for existence. Lesson Plan Teaching Photosynthesis And Cellular Respiration In . Protists, bacteria and blue-green algae are other organisms that photosynthesize for nourishment. Photosynthesis plays a vital role in our environment.

Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. Copyright 2021 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. The photosynthesizing plants produce many economically useful products. This leads to synthesis ample amount of carbohydrate for the plant. Without plants, life as we know it would not exist on our planet. Finally, we will describe the process with suitable equations. To be specific, they are a much larger group of pigments. It contributes to the symbiotic relationship between plants, humans and animals. This is the reason that plants appear green to us. Furthermore, carbon dioxide and water drives these processes. Both the processes are inter-related, and serve one another. Carbon dioxide, which is otherwise utilized by the plants during the photosynthesis to produce carbohydrates, remains in the atmosphere when the trees and plants are cut down. The overall balanced formula of photosynthesis is: The end products of photosynthesis are glucose (starch and sucrose) and oxygen. Directly or indirectly, photosynthesis fills all of our food requirements and many of our needs for fiber and building materials. Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Cellular respiration is a three-step process. This is true to all the animals including heterotrophs and saprotrophs, for instance. Chlorophyll specifically absorbs light from the red and blue parts of the light spectrum, and reflects green light. Enter your email address and spin the wheel. The importance of photosynthesis in our life is the oxygen it produces. While most plants use photosynthesis to produce energy, there are some that are non-photosynthetic. Photosynthesis uses light energy from the sun and carbon dioxide and water in the atmosphere to make food for plants, trees, algae and even some bacteria. Photosynthesis and Important ? Plants that do not use photosynthesis to produce food are usually parasitic, which means they rely on a host for nutrient generation. All producers make oxygen and sugar for the secondary consumers and then the carnivores eat animals that eat the plants. These are Chlorophyll a, b, c, d and bactriochlorophyll. Let us learn each stage in detail. It’s not particularly efficient by human engineering standards, but it does the job. The following equation depicts the whole process, for instance. The chemistry and physics are complex. Why is photosynthesis important? This energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Cellular respiration allows all living cells to extract energy in the form of ATP from food and offer that energy for the vital processes of life. The chlorophyll a absorbs light in the blue-violet region whereas chlorophyll b absorbs red-blue light. Here, the electrons are passed from one component to the other. Examples include Indian pipe (Monotropa uniflora) – also known as the ghost or corpse plant – and beechdrops (Epifagus americana), which steals nutrients found in beech tree roots. Atmospheric gases. Photosynthesis has much importance to pl​ants such as: #1. To summarize, photosynthesis occurs in four different stages involving two complete cycles. Photosynthesis is an energy-storing process that is important to animals as it is to plants. Photosynthesis is the process in which light energy is transformed into chemical energy. However, the reactions of this stage are indirectly dependent on light energy. Therefore, chlorophyll pigment appears green in color. During photosynthesis, the chemical energy is used to obtain organic compounds from carbon dioxide. 1134 Words 5 Pages. Photosynthesis is also an important factor in reducing the damage many scientists worry about du… Since plants lack a complete immune system, they serve as immune response cells. The Importance of Photosynthesis and Respiration Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat: Photosynthesis is the process in which certain life forms are able to use sunlight to create energy. This is applicable to plants as well as animals. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. In this article, you will learn all you need to know about photosynthesis. Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. (Campbell, pg. According to my reading, energy is the strength and vitality to sustain physical or mental activity as it relates to humans (McKean, 1995).Energy is intertwined in all living things because plants are eaten by herbivores, and meat eaters or carnivores eat herbivores and other animals. By now, we already know that photosynthesis is a physio-chemical process that transforms light energy to chemical energy. Nearly every life depends on this process. It releases oxygen as a byproduct.

Let us now learn the different stages involved in photosynthesis. The Carbon Cycle would cease to occur without photosynthesis. Now photosynthesis is something that is performed creatively by organisms such as plants, algae, and some bacteria. Problem 1RQ from Chapter 16: What is the importance of photosynthesis to plants and animals? It is the location for light reactions and dark reactions. Plants, algae and bacteria are the only organisms that can harvest sunlight and use the energy to convert CO 2 (carbon dioxide) to organic material. Importance of bacterial photosynthesis: The most important usefulness of photobacteria is in analysis of evolution of photosynthetic systems. The Importance of Carbon Dioxide in Photosynthesis Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize food from carbon dioxide and water. Therefore, photosynthesis is an indispensable factor to keep the life cycle uninterrupted. The chlorophyll pigment attached to proteins in the thylakoid membranes performs this process. As a result, it is termed as ‘The Dark Phase’. Today we are alive because of photosynthesis, it is the only natural process which uses sunlight for the production of food. Photosynthesis is arguably the most important biological process on earth. Additionally, it connects the stacks of thylakoids. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. Photosynthesis is the only process by which solar energy is converted into chemical energy. The chloroplasts within the plant store the chlorophyll, and these are found in the mesophyll layer of … The Importance Of Photosynthesis. By liberating oxygen and consuming carbon dioxide, it has transformed the world into the hospitable environment we know today. If photosynthesis does not occur in plants then plants cannot synthesize the food. The importance of photosynthesis. It also gives an evolutionary evidence for origin of chloroplasts. ATP is crucial in the relationship between energy and living things, and is known as the "energy currency for all life.". In short, the very existence of life on earth will be in danger. Before asking that question You should ask another question : Why is it important to eat? A lizard sunning itself on a cold day can use the sun’s energy to warm up. Made up of thylakoids which are stacks of disc shaped structures. Therefore, they depend directly or indirectly on plants for their food. Free energy from sunlight is captured and stored as sugars and starches in plant tissues. It is type of plastid exclusive to the plant cell. 805 Words 4 Pages. However, they are classified as light dependent and light independent stages conveniently. Brenner is also a published sci-fi author. (Citovsky, Lecture 10). 175). Consequently, these reactions liberates oxygen into the atmosphere. Photosynthesis are composed of light reactions and Calvin cycle. Furthermore, it involves various reactions. The chlorophyll in these living organisms, which also contributes to their green hues, absorbs the sunlight and combines it with carbon dioxide to convert these compounds into an organic chemical called adenosine triphosphate (ATP). Importance of Photosynthesis Photosynthesis is essential for the existence of all life on earth. They are the primary producers. Solved Dy Lab 6 Prelab Photosynthesis And Celluar Respi. Contains the grana along with DNA, ribosomes, etc. There are basically four stages in the photosynthetic process. Additionally, it is often called the Calvin Cycle. Apart from transforming carbon dioxide to oxygen, photosynthesis also plays a major role in maintaining the food chain. Furthermore, there are five important types of chlorophylls. Show More. The electrons move from a higher energy level to a lower energy level. This continues until the end of chain where NADPH is obtained. These together make up over 85 percent of humans' energy use. All living cells in plants, animals and humans take part in cellular respiration in one form or another. It is the number one source of oxygen in the atmosphere. In short, this production of high energy ATP and NADPH in plants occur in the presence of light. Her stint as Manager of the California State Mining and Mineral Museum in California's gold country served to deepen her interest in science which she now fulfills by writing for online science websites. However, this chain reaction continues until they reach the ultimate electron acceptor. Green plants play a vital role in the following areas. The whole life form is directly or indirectly dependent on the process of photosynthesis carried out by plants. The sugars are used by the cell as energy, and to build other kinds of molecules. Get solutions That is why, it is true to say that photosynthesis is essential for the existence on life on our plant itself! However, in photosynthesis carotenoid pigments function as reliable molecules to dispose excess energy. Subsequently, this process liberates oxygen. Hence, if they do not undergo photosynthesis, all the other organisms which are directly and indirectly dependent on the plants for food, will find it hard to survive. The third step of cellular respiration involves oxygen and is called aerobic respiration, in which the food energy enters an electron transport chain where it produces ATP. Photosynthesis is a physio-chemical process by which plants prepare food with the help of carbon dioxide and water, in the presence of sunlight and chlorophyll. In simple terms, photosynthesis absorbs carbon dioxide and emits oxygen in the air. This include Algae, cyanobacteria and certain sulfur bacteria, for instance. The way leaves are arranged on stems ensures that the plant takes maximum advantage of available light. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth. Colorless, aqueous, protein-rich fluid which is similar to cytoplasm. Besides leaves, plant parts like green stem and green branch can also take part in photosynthesis. Photosynthesis can therefore be considered as the reverse of respiration. Sugars and other carbon compounds are synthesized by this chemical energy. These decayed remains are subjected to geological processes, such as heat and pressure, for millions of years to become coal, oil and natural gas. Photosynthesis is very important for life on Earth. Photosynthesis is so important that, without it, there wouldn’t be life on Earth. It is ecologically important to remove the excess carbon dioxide in nature. Tiny pores, or stomata, are also located on the plant's leaves and absorb carbon dioxide from the surrounding air. Which Is More Important Photosynthesis Or Cellular Respiration. The chloroplasts have important functions to perform, in particular. The key to photosynthesis is the chloroplast. Molecules of glucose later combine with each other to form more complex carbohydrates such as starch and cellulose. Photosynthesis is plants taking in water, carbon dioxide, and light to make sugar and oxygen.This is important because all living things need oxygen to survive. It helps to create a proton gradient. The food is in the form of carbohydrates. Photosynthesis is an important biochemical pathway involving the production of sugar (glucose) from light, water and carbon dioxide and releasing oxygen. Without green plants performing photosynthesis there would be no way for … Get free mock test for General Science! This include, paper, cotton and natural fibres for instance. Plants release … They produce energy in the form of ATP and NADPH. Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. The main function of the energy absorbed by light is to remove electrons from water. Plants produce glucose during photosynthesis which plays a vital role in its growth. They are the site of photosynthesis in eukaryotic cells (including plants and algae). Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. She graduated from San Diego's Coleman College in 1972. The importance of Photosynthesis Another Importance to Photosynthesis is, It is important to life on Earth because we all breathe in the oxygen that the plants produce for us. It is because, plants are the sole autotrophs in the planet. This is the second step in photosynthesis which is light driven. Carbon dioxide is needed for photosynthesis. Apart from plants, there are a few other species that can undergo photosynthesis. They are the primary producers. The importance of … It is because, plants are the sole autotrophs in the planet. The main benefit of photosynthesis to plants is that they are able to produce their own food. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis is an important activity that occurs in all green plants, whether flowering or non- flowering. It is very essential. This is the final step in the photosynthetic process. A plant uses the carbon dioxide exhaled by animals and humans in combination with the sun's energy during cellular respiration to produce the food that it requires. It directly or indirectly affects most life on Earth. Importance of Photosynthesis in Life Cellular respiration in plants is essentially the opposite of photosynthesis. During photosynthesis plants take in carbon dioxide and give off oxygen as a by-product. In the second step, the cell transports the pyruvate molecules into the mitochondria, the energy center of the cells, without using oxygen, This is known as anaerobic respiration. To sum up, photosynthesis helps to harness the sun’s energy into useful and utilizable forms of energy on earth. Plants in the fungi kingdom – mushrooms, molds and yeasts – rely on their environment for food instead of photosynthesis. It is the initial step in the process of photosynthesis. 7 What is the importance of photosynthesis for all life 8 How is energy from MATH AICE at William T. Dwyer High School Another importance is; The food in the plants can then be eaten by animals, since animals cannot convert solar energy to glucose, photosynthesis creating energy becomes very helpful in our animal life and humans. Given below are some of them. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The importance of photosynthesis can be understood with respect to our breathing process. Photosynthesis is one of the most important contributors to numerous of things, ranging from maintaining the ecosystem stable to producing oxygen for the entire world. Photosynthesis is important for the existence of life on earth. Carbon dioxide is one of the major air pollutants, so photosynthetic organisms are actually keeping the air clean. In addition to this, oxygen is the by-product of this process. Photosynthesis is vital because it evolved as a way to store the energy in solar radiation (the “photo-” part) as high-energy electrons in the carbon-carbon bonds of carbohydrate molecules (the “-synthesis” part). Furthermore, the green plants on earth have a unique ability to produce their own food. Show More. It serves a crucial role in the food chain – the plants create their food using this process, thereby, forming the primary producers. Photosynthesis is an essential reaction that can be carried by chloroplast in the plant. It may even lead to disappearing of many animals from earth.

In this article, you will learn all you need to know about photosynthesis. Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. (Campbell, pg. According to my reading, energy is the strength and vitality to sustain physical or mental activity as it relates to humans (McKean, 1995).Energy is intertwined in all living things because plants are eaten by herbivores, and meat eaters or carnivores eat herbivores and other animals. By now, we already know that photosynthesis is a physio-chemical process that transforms light energy to chemical energy. Nearly every life depends on this process. It releases oxygen as a byproduct.

Let us now learn the different stages involved in photosynthesis. The Carbon Cycle would cease to occur without photosynthesis. Now photosynthesis is something that is performed creatively by organisms such as plants, algae, and some bacteria. Problem 1RQ from Chapter 16: What is the importance of photosynthesis to plants and animals? It is the location for light reactions and dark reactions. Plants, algae and bacteria are the only organisms that can harvest sunlight and use the energy to convert CO 2 (carbon dioxide) to organic material. Importance of bacterial photosynthesis: The most important usefulness of photobacteria is in analysis of evolution of photosynthetic systems. The Importance of Carbon Dioxide in Photosynthesis Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize food from carbon dioxide and water. Therefore, photosynthesis is an indispensable factor to keep the life cycle uninterrupted. The chlorophyll pigment attached to proteins in the thylakoid membranes performs this process. As a result, it is termed as ‘The Dark Phase’. Today we are alive because of photosynthesis, it is the only natural process which uses sunlight for the production of food. Photosynthesis is arguably the most important biological process on earth. Additionally, it connects the stacks of thylakoids. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. Photosynthesis is the only process by which solar energy is converted into chemical energy. The chloroplasts within the plant store the chlorophyll, and these are found in the mesophyll layer of … The Importance Of Photosynthesis. By liberating oxygen and consuming carbon dioxide, it has transformed the world into the hospitable environment we know today. If photosynthesis does not occur in plants then plants cannot synthesize the food. The importance of photosynthesis. It also gives an evolutionary evidence for origin of chloroplasts. ATP is crucial in the relationship between energy and living things, and is known as the "energy currency for all life.". In short, the very existence of life on earth will be in danger. Before asking that question You should ask another question : Why is it important to eat? A lizard sunning itself on a cold day can use the sun’s energy to warm up. Made up of thylakoids which are stacks of disc shaped structures. Therefore, they depend directly or indirectly on plants for their food. Free energy from sunlight is captured and stored as sugars and starches in plant tissues. It is type of plastid exclusive to the plant cell. 805 Words 4 Pages. However, they are classified as light dependent and light independent stages conveniently. Brenner is also a published sci-fi author. (Citovsky, Lecture 10). 175). Consequently, these reactions liberates oxygen into the atmosphere. Photosynthesis are composed of light reactions and Calvin cycle. Furthermore, it involves various reactions. The chlorophyll in these living organisms, which also contributes to their green hues, absorbs the sunlight and combines it with carbon dioxide to convert these compounds into an organic chemical called adenosine triphosphate (ATP). Importance of Photosynthesis Photosynthesis is essential for the existence of all life on earth. They are the primary producers. Solved Dy Lab 6 Prelab Photosynthesis And Celluar Respi. Contains the grana along with DNA, ribosomes, etc. There are basically four stages in the photosynthetic process. Additionally, it is often called the Calvin Cycle. Apart from transforming carbon dioxide to oxygen, photosynthesis also plays a major role in maintaining the food chain. Furthermore, there are five important types of chlorophylls. Show More. The electrons move from a higher energy level to a lower energy level. This continues until the end of chain where NADPH is obtained. These together make up over 85 percent of humans' energy use. All living cells in plants, animals and humans take part in cellular respiration in one form or another. It is the number one source of oxygen in the atmosphere. In short, this production of high energy ATP and NADPH in plants occur in the presence of light. Her stint as Manager of the California State Mining and Mineral Museum in California's gold country served to deepen her interest in science which she now fulfills by writing for online science websites. However, this chain reaction continues until they reach the ultimate electron acceptor. Green plants play a vital role in the following areas. The whole life form is directly or indirectly dependent on the process of photosynthesis carried out by plants. The sugars are used by the cell as energy, and to build other kinds of molecules. Get solutions That is why, it is true to say that photosynthesis is essential for the existence on life on our plant itself! However, in photosynthesis carotenoid pigments function as reliable molecules to dispose excess energy. Subsequently, this process liberates oxygen. Hence, if they do not undergo photosynthesis, all the other organisms which are directly and indirectly dependent on the plants for food, will find it hard to survive. The third step of cellular respiration involves oxygen and is called aerobic respiration, in which the food energy enters an electron transport chain where it produces ATP. Photosynthesis is a physio-chemical process by which plants prepare food with the help of carbon dioxide and water, in the presence of sunlight and chlorophyll. In simple terms, photosynthesis absorbs carbon dioxide and emits oxygen in the air. This include Algae, cyanobacteria and certain sulfur bacteria, for instance. The way leaves are arranged on stems ensures that the plant takes maximum advantage of available light. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth. Colorless, aqueous, protein-rich fluid which is similar to cytoplasm. Besides leaves, plant parts like green stem and green branch can also take part in photosynthesis. Photosynthesis can therefore be considered as the reverse of respiration. Sugars and other carbon compounds are synthesized by this chemical energy. These decayed remains are subjected to geological processes, such as heat and pressure, for millions of years to become coal, oil and natural gas. Photosynthesis is very important for life on Earth. Photosynthesis is so important that, without it, there wouldn’t be life on Earth. It is ecologically important to remove the excess carbon dioxide in nature. Tiny pores, or stomata, are also located on the plant's leaves and absorb carbon dioxide from the surrounding air. Which Is More Important Photosynthesis Or Cellular Respiration. The chloroplasts have important functions to perform, in particular. The key to photosynthesis is the chloroplast. Molecules of glucose later combine with each other to form more complex carbohydrates such as starch and cellulose. Photosynthesis is plants taking in water, carbon dioxide, and light to make sugar and oxygen.This is important because all living things need oxygen to survive. It helps to create a proton gradient. The food is in the form of carbohydrates. Photosynthesis is an important biochemical pathway involving the production of sugar (glucose) from light, water and carbon dioxide and releasing oxygen. Without green plants performing photosynthesis there would be no way for … Get free mock test for General Science! This include, paper, cotton and natural fibres for instance. Plants release … They produce energy in the form of ATP and NADPH. Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. The main function of the energy absorbed by light is to remove electrons from water. Plants produce glucose during photosynthesis which plays a vital role in its growth. They are the site of photosynthesis in eukaryotic cells (including plants and algae). Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. She graduated from San Diego's Coleman College in 1972. The importance of Photosynthesis Another Importance to Photosynthesis is, It is important to life on Earth because we all breathe in the oxygen that the plants produce for us. It is because, plants are the sole autotrophs in the planet. This is the second step in photosynthesis which is light driven. Carbon dioxide is needed for photosynthesis. Apart from plants, there are a few other species that can undergo photosynthesis. They are the primary producers. The importance of … It is because, plants are the sole autotrophs in the planet. The main benefit of photosynthesis to plants is that they are able to produce their own food. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis is an important activity that occurs in all green plants, whether flowering or non- flowering. It is very essential. This is the final step in the photosynthetic process. A plant uses the carbon dioxide exhaled by animals and humans in combination with the sun's energy during cellular respiration to produce the food that it requires. It directly or indirectly affects most life on Earth. Importance of Photosynthesis in Life Cellular respiration in plants is essentially the opposite of photosynthesis. During photosynthesis plants take in carbon dioxide and give off oxygen as a by-product. In the second step, the cell transports the pyruvate molecules into the mitochondria, the energy center of the cells, without using oxygen, This is known as anaerobic respiration. To sum up, photosynthesis helps to harness the sun’s energy into useful and utilizable forms of energy on earth. Plants in the fungi kingdom – mushrooms, molds and yeasts – rely on their environment for food instead of photosynthesis. It is the initial step in the process of photosynthesis. 7 What is the importance of photosynthesis for all life 8 How is energy from MATH AICE at William T. Dwyer High School Another importance is; The food in the plants can then be eaten by animals, since animals cannot convert solar energy to glucose, photosynthesis creating energy becomes very helpful in our animal life and humans. Given below are some of them. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The importance of photosynthesis can be understood with respect to our breathing process. Photosynthesis is one of the most important contributors to numerous of things, ranging from maintaining the ecosystem stable to producing oxygen for the entire world. Photosynthesis is important for the existence of life on earth. Carbon dioxide is one of the major air pollutants, so photosynthetic organisms are actually keeping the air clean. In addition to this, oxygen is the by-product of this process. Photosynthesis is vital because it evolved as a way to store the energy in solar radiation (the “photo-” part) as high-energy electrons in the carbon-carbon bonds of carbohydrate molecules (the “-synthesis” part). Furthermore, the green plants on earth have a unique ability to produce their own food. Show More. It serves a crucial role in the food chain – the plants create their food using this process, thereby, forming the primary producers. Photosynthesis is an essential reaction that can be carried by chloroplast in the plant. It may even lead to disappearing of many animals from earth.
