Photosynthesis

Photosynthesis is the process whereby plants using light energy to 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 ==> glucose + oxygen

6CO₂ + 6H₂O ==> C₆H₁₂O₆ + 6O₂
 

Photosynthesis is carried out in the chloroplasts of plant cells using the green pigment chlorophyll. The glucose produced is converted into starch. Starch is a polymer made up of repeating glucose units.
