Photosynthesis is the process of plants getting food, making sugar, and releasing carbon dioxide. First the sun gives off light energy and the plant collects it through its leaves. Then the plant traps the light energy to make food. The plant also has chlorophyll in it to make the plant green. Another way plants get nutrients is water through its roots. After the plant traps the light energy, oxygen enters the stomata of the leaf. The oxygen then goes to the chlorophyll and is mixed with other materials to make glucose and carbon dioxide The plant breathes out the carbon dioxide and keeps the sugar for food. The chemical equation for glucose is C6H12O6
Cellular respiration is where stored energy is broken down to release energy. The reactants are sugar, oxygen and carbon dioxide and the products are water and energy. First the plant breathes in oxygen and stores it. Then it makes sugar and carbon dioxide. The plant keeps the sugar for food and releases carbon dioxide to make water and energy.
