Photosynthesis – What Is Photosynthesis?, Meaning, Definition, Equation Photosynthesis Definition: Photosynthesis is a Greek word, wherein, Photo means light, synthesis means putting together. The sugars are used by the cell as energy, and to build other kinds of molecules. It is the process by which green plants, algae, and certain bacteria convert light energy from the sun into chemical energy that is used to make glucose. It involves a chemical reaction where water, carbon dioxide, chlorophyll, and solar energy are utilized as raw materials (inputs) to produce glucose, oxygen, and water (outputs). The chemical equation that explains photosynthesis is: 6C0 2 +12 H 2 0 + light energy → C 6 H 12 O 6 +6O 2 +6 H 2 O. But green plants and algae do not. Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates. Photosynthesis as a combination of the two reactions can be summarized with this expression: But if plants can produce ATP through photosynthesis, then why do they need to respire? IT'S BALANCED EQUATION : 6 CO2 (Carbondioxide ) + 12 H20 ( water) -----> C6 H12 06 ( glucose) + 6 H20 (water) + 6 O2 ( oxygen) To emphasize this point even more, the equation for photosynthesis is the opposite of cellular respiration. Photosynthesis Chemical Equation. Subject: Biology. 6CO2 + 12 H2O → Light and chlorophyll → C6H12O6 + 6H2O + 6O2. Photosynthesis is where the plant produces glucose and oxygen by using CO2, water. Ans. 2) The Light-independent or Dark Reaction (Calvin cycle). Photosynthesis Definition. © 2021 (Science Facts). This glucose can be … The rate of photosynthesis can also be measured by determining the increase in the plant’s biomass (weight). The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide. The general equation for photosynthesis as first proposed by Cornelis van Niel is therefore: CO 2 carbon dioxide + 2H 2 A electron donor + photons light energy → [CH 2 O] carbohydrate + 2A oxidized The formula for photosynthesis is 6CO2 + 6H2O + light energy = C6H12O6 + 6O2. State which organisms undergo photosynthesis. Photosynthesis definition states that the process exclusively takes place in the chloroplasts through photosynthetic pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll. The process of photosynthesis occurs in two steps. The word ‘photosynthesis’ is derived from the Greek word phōs, meaning ‘light’ and synthesis meaning ‘combining together.’ Ans. Define Photosynthesis with the Equation of this Process with Explanation. The chemical equation for photosynthesis involves the input (reactants) of carbon dioxide, water, and sunlight to produce the outputs (products) of glucose and oxygen. The chemical equation for photosynthesis involves the input (reactants) of carbon dioxide, water, and sunlight to produce the outputs (products) of glucose and oxygen. Now back to the definition… Earlier you learned that photosynthesis is the process by which plants make their own food. See more. Explanation: The equation of photosynthesis can be explained in the following ways: © copyright 2020 QS Study. The easiest way to measure the rate of photosynthesis is to quantify the carbon dioxide or oxygen levels using a data logger. The equation below is the same as the one above but it shows the chemical formula for carbon dioxide, water, glucose and oxygen. Apart from plants, photosynthesis is also found to occur in blue-green algae. Photosynthesis Formula Breakdown. Ans. The simplified equation used to represent this overall process is 6CO 2 +12H 2 O+energy=C 6 H 12 O 6 +6O 2 +6H 2 O It is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. Interactive In addition to this, oxygen is the by-product of this process. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Article was last reviewed on Tuesday, April 21, 2020, Your email address will not be published. Photosynthesis is an endothermic reaction because it absorbs the heat of the sun to carry out the process. Topic: Physiology of Plant. The requisite source for photosynthesis is Sunlight. The sunlight is received by receptors present in the leaves, where, Dark Reaction and Light … Plants, algae and cyanobacteria release oxygen during photosynthesis. Photosynthesis is the fundamental process by which plants manufacture food molecules (carbohydrates) from raw materials CO2 and H2O) using energy from light. Photosynthesis Definition Photosynthesis is defined as the process, utilized by green plants and photosynthetic bacteria, where electromagnetic radiation is converted into chemical energy and uses light energy to convert carbon dioxide and water into carbohydrates and oxygen. H2O … Learn more. Apart from plants, photosynthesis is also found to occur in blue-green algae. 2. Oxygen is formed in the proceess as a by-product and is released to the atmosphere through stomata. This chemical process is a fundamental equation for understanding how photosynthesis compliments respiration. Chlorophyll is the main light-absorbing pigment in photosynthesis.
