Every living creature needs food or energy to survive. Some depend on others for food and energy, whiles others can produce their own food.Plants make their own food, glucose, in a process called photosynthesis. We say that plants can photosynthesise.Photosynthesis and respiration go hand in hand. The result of photosynthesis is glucose, which is stored as chemical energy in the plant cells. This stored chemical energy comes from the conversion of inorganic carbon (carbon dioxide) into organic carbon. Respiration releases the stored chemical energy.
