How does photosynthesis work?
Photosynthesis is the process by which plants and some other organisms use light energy to convert carbon dioxide and water into organic compounds like sugars. The process begins when light energy from the sun is absorbed by pigments in the chloroplasts of plant cells, which then convert it into chemical energy. This energy is used to convert carbon dioxide and water into glucose (sugar) molecules. These glucose molecules are then used as a source of energy for the organism.
