Photosynthesis is the process by which plants convert light energy into chemical energy. It occurs in two main stages: the light-dependent reactions and the light-independent reactions (Calvin cycle). During the light-dependent reactions, chlorophyll absorbs light energy...

The main products of photosynthesis are glucose (C₆H₁₂O₆) and oxygen (O₂). The overall equation is: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂
