How does photosynthesis work?

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy. They use sunlight, carbon dioxide, and water to produce glucose and oxygen.

What are the main stages of photosynthesis?

Photosynthesis occurs in two main stages: the light-dependent reactions and the light-independent reactions (Calvin cycle). The light-dependent reactions capture energy from sunlight, while the Calvin cycle uses that energy to convert carbon dioxide into glucose.

Can you explain the light-dependent reactions in detail?

Sure! The light-dependent reactions take place in the thylakoid membranes of chloroplasts. When sunlight hits chlorophyll, it excites electrons, which then move through a series of proteins, creating ATP and NADPH while splitting water molecules to release oxygen.

What role does chlorophyll play in photosynthesis?

Chlorophyll is the green pigment in plants that absorbs light energy, primarily in the blue and red wavelengths. It plays a crucial role in capturing sunlight for the light-dependent reactions of photosynthesis.
