photosynthesis
photosynthesis Term given to the series of metabolic reactions that occur in certain autotrophic organisms, whereby organic compounds are synthesized by the reduction of carbon dioxide using energy absorbed by chlorophyll from sunlight. In green plants, where water acts both as a hydrogen donor and as a source of released oxygen, photosynthesis may be summarized by the empirical equation: chlorophyll
CO
2 + 2H
2O → [CH
2O] + H
2O + O

(oxygen being released as a gas). Photosynthetic bacteria are unable to utilize water and therefore do not produce oxygen. Instead they may use hydrogen sulphide (purple and green sulphur bacteria) or organic compounds (purple non-sulphur bacteria) as a source of hydrogen.
