photosynthesis

the process by which plants convert carbon dioxide and water into organic chemicals using the energy of light, with the release of oxygen. Photosynthesis occurs in green plants which are known as AUTOTROPHS. CYANOBACTERIA also carry out photosynthesis. See LIGHT REACTIONS and CALVIN CYCLE.
