Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose molecules. This process involves the absorption of light by chlorophyll in chloroplasts, which triggers a series of chemical reactions that ultimately produce glucose. Photosynthesis is important because it is the primary way in which plants produce their own food, providing energy for growth and development. Additionally, photosynthesis releases oxygen as a byproduct, which is essential for the survival of most living organisms on Earth.
