Summary Introduction
Introduction:
The process of photosynthesis is required for the conversion of carbon dioxide and water molecules into the sugars, and oxygen. Photosynthesis is not done in a single step rather it is a two-stage reaction. The reactions that are involved in photosynthesis pathway are light-dependent reactions, and light-independent reactions.
