Oxygen is a by-product of this process. Photosynthesis is vital for life on earth, as it maintain the normal level of oxygen in the atmosphere. All life depends on photosynthesis directly as a source of energy or indirectly as the ultimate source of the energy in their food. Photosynthesis is also the source of carbon in all the living form. Most of the plants have green pigment called, chlorophyll, in their leaves. Chlorophyll gives the green colour of the leaf, helps in photosynthesis. It is the chlorophyll that helps the plants to trap the energy from the sunlight for making their food.
