Photosynthesis is the process whereby plants using light energy from the sun convert carbon dioxide and water to glucose sugar and oxygen gas through a series of reactions. The overall equation for photosynthesis is. carbon dioxide + water =light energy=> glucose + oxygen. 6CO2 + 6H2O =light energy=> C6H12O6 + 6O2. Light energy from the sun is converted into chemical energy by the production of glucose molecules. Photosynthesis is carried out in the chloroplasts of plant cells using the green pigment chlorophyll.
Photosynthesis. The manufacture in light of organic compounds (primarily certain carbohydrates) from inorganic materials by chlorophyll-or bacteriochlorophyll-containing cells. This process requires a supply of energy in the form of light. In chlorophyll-containing plant cells and in cyanobacteria, photosynthesis involves oxidation of water (H 2 O) to oxygen molecules, which are released into the environment.
