Photosynthesis is the process whereby plants using light energy from the sun convert carbon dioxide and water to glucose sugar and oxygen gas through a series of reactions. The overall equation for photosynthesis is. carbon dioxide + water =light energy=> glucose + oxygen. 6CO2 + 6H2O =light energy=> C6H12O6 + 6O2. Light energy from the sun is converted into chemical energy by the production of glucose molecules. Photosynthesis is carried out in the chloroplasts of plant cells using the green pigment chlorophyll.
Photosynthesis is the conversion of carbon dioxide and water into carbohydrates using energy from sunlight. It is the main process by which new energy becomes available to life on Earth. Plants and algae use photosynthesis to convert light energy into a form available to other organisms, and thus form the base of almost every food chain.
