Photosynthesis

Photosynthesis is the process by which plants make their own food. For this to happen plants need carbon dioxide, water and sunlight. The way it works is that carbon dioxide passes through pores in the leaves. When this happens water is absorbed by the roots and goes in the stem of the leaf. At this point sunlight is absorbed by a green chemical called chlorophyll. There are two stages that occur in photosynthesis, Calvin Cycle and light dependent reactions. Light dependent reactions can only happen when light is available. During these reactions light energy is converted to chemical energy. The Calvin Cycle occurs in the stroma of the chloroplasts and is light independent. It takes place after the energy has been captured from the sunlight. The purpose of photosynthesis is so we have food and oxygen, us humans can not live without it
