How does photosynthesis work?

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 sunlight to produce energy carriers, while the Calvin cycle uses those carriers to synthesize glucose.

Why is photosynthesis important for life on Earth?

Photosynthesis is crucial because it produces oxygen, which is essential for most life forms, and it forms the base of the food chain by converting solar energy into chemical energy.

Can you explain the role of chlorophyll in photosynthesis?

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the blue and red wavelengths, which is essential for the light-dependent reactions of photosynthesis.

What factors affect the rate of photosynthesis?

The rate of photosynthesis can be affected by several factors, including light intensity, carbon dioxide concentration, temperature, and the availability of water.
