Photosynthesis, is the process whereby light energy is transform into chemical energy by
green plants and other photosynthesis capable organisms . In the process of photosynthesis, light energy is captured by green plants which it uses to convert carbon dioxide water, and minerals into energy-rich organic compounds and oxygen is evolved as a byproduct.
It is a chemical reaction taking place inside a plant, resulting in the production of food for the survival of the plant.
Photosynthesis takes place in the leaves of a plant in the presence of sunlight and.
