Photosynthesis is the process by which green plants convert light energy into chemical energy stored in glucose molecules. It occurs mainly in the chloroplasts of plant cells. The process involves two main stages:

• Light-dependent reactions: Chlorophyll absorbs light energy, which excites electrons. Water molecules are split (photolysis) to release oxygen, protons, and electrons. This process generates ATP and NADPH.
• Light-independent reactions (Calvin Cycle): Using ATP and NADPH, atmospheric carbon dioxide is fixed into glucose through a series of enzyme-mediated reactions.

Significance:

• Produces oxygen necessary for respiration.
• Converts solar energy into chemical energy.
• Forms the base of the food chain.
