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.
The process of photosynthesis is divided into two main parts. The first part is called the light dependent reaction. This reaction happens when the light energy is captured and pushed into a chemical called ATP. The second part of the process happens when the ATP is used to make glucose (the Calvin Cycle). That second part is called the light independent reaction.
