As we all know that plants are able to make their own food and therefore they are known as autotrophs. This ability of plants to make their own food help sustain living organisms on the planet Earth. The process by which plants make their food is known as photosynthesis. Photosynthesis form and integral part of the function of plants. In this process plants use raw material such as sunlight water and carbon dioxide from the air and chlorophyll pigment present in the leaves of the plant to make their food. Therefore we can conclude that chlorophyll is a very important pigment that help the plants in making their food and without which It wouldn’t be possible for plants to prepare their food. This pigment is present in the leaves of the plant and helps the plant to tap sunlight and use the energy from it.
Chlorophyll is the molecule that absorbs sunlight and uses its energy to synthesise carbohydrates from CO<sub>2</sub> and water.
Does the chlorophyll pigment is very important from living organisms and not only for plant as if plants do not prepare food the humans will also not be able to get food and similarly all the animals will also die of starvation. Since plants form the most integral part of food chain therefore chlorophyll pigment forms one of the most important components of human as well as plant life.
It is because of the chlorophyll pigment that the leaves of the plant look green. The variation in colour is due to different amount of chlorophyll pigment present in the leaves some plants have large amount of chlorophyll in their leaves while other others may have less.
