(3) Photosynthesis is the processof converting light energyto chemical energy and storingit in the bonds of carbohydrates(sugar). The main productof photosynthesis is glucose,which is the moleculethat produces energy to run theprocesses of the cell. Oxygenis mainly a byproduct of theprocess of photosynthesis.6H2O (water) + 6CO2(carbondioxide) = C6H12O6 (glucose) +6O2 (oxygen
