Chlorophyll is the green colouring of leaves which are vital to green plants. This helps the plants to make their food. This is also reponsible for the colours in plants such as red in carrots. Plants which have no chlorophyll depend on other plants for food and are called parasites.
Chlorophyll absorbs sunlight and uses its energy to synthesise carbohydrates from CO2 and water. During this process of photosynthesis, chlorophyll produces energy, in the form of carbohydrates, which will power all of the plant's essential growth and development.
