Photosynthesis is a process in which solar energy is converted into chemical energy such as glucose molecule. Photosynthesis is a process in which carbondioxide is taken inside the plant body through a tiny holes called stomata and water is absorbed by the plant from the soil through roots. Both carbondioxide and water are reactants in photosynthesis. When they combine with each other in the presence of sunlight, oxygen and glucose are produced.

Carbondioxide + water - - - - oxygen +glucose.
