Photosynthesis is the biochemical process by which green plants, algae, and certain bacteria convert light energy, usually from the sun, into chemical energy stored in glucose. This process is fundamental for life on Earth as it forms the basis of the food chain and is responsible for the oxygen in our atmosphere. Photosynthesis occurs primarily in the chloroplasts of plant cells, where the pigment chlorophyll absorbs light energy. The process involves two main stages: the light-dependent reactions and the Calvin cycle (light-independent reactions). During the light-dependent reactions, sunlight is absorbed, and its energy is used to split water molecules, releasing oxygen and transferring energy to the molecules ATP and NADPH. In the Calvin cycle, this energy is used to convert carbon dioxide from the atmosphere into glucose, which can be used by the plant for energy and growth. Photosynthesis not only sustains plant life but also supports all other life forms by providing oxygen and organic compounds needed for survival.
