A Beginner's Guide to Photosynthesis

TLDRPhotosynthesis is a process that uses light energy to convert water and carbon dioxide into glucose and oxygen. It takes place in the chloroplasts of plant cells and involves two main stages: the light-dependent reactions and the light-independent reactions. The light-dependent reactions produce ATP and NADPH, while the light-independent reactions use these energy-rich molecules to fix carbon dioxide and produce glucose. Photosynthesis is essential for life on Earth as it is the primary source of oxygen and food.
