photosynthesis
photosynthesis Chemical process occurring in green plants, algae, and many bacteria, by which water and carbon dioxide convert into food and oxygen using energy absorbed from sunlight. The reactions take place in the
chloroplasts, which are microscopic green structures. During the first part of the process, the green pigment
chlorophyll absorbs light and splits water into hydrogen and oxygen. The hydrogen attaches to a carrier molecule and the oxygen is set free. The hydrogen and light energy build a supply of cellular chemical energy,
adenosine triphosphate (ATP). Hydrogen and ATP convert the carbon dioxide into sugars, including glucose and starch.
