Look at trees and other plant, and what colour do you see? The answer, almost always, is various shades of green. That green colour is produced by a chemical called chlorophyll, which is found on the leaves of plants. Chlorophyll is the one of the most important substance on Earth, because it absorbs energy from sunlight, and enables plants to grow. Without it, plants could not survive, and animals would have nothing to eat.
How do plants feed?
Unlike animals, plants do not need to find food. Instead, they make food 'out of thin air' with the help of chlorophyll. The chlorophyll in the plant's leaves absorbs energy from sunshine. The plant then uses this energy to combine water with carbon dioxide, making a sugary food substance called glucose. This process is called photosynthesis. Plants use glucose to grow.They also use it to form sweet-tasting fruits, and to make nectar, syrupy liquid that attracts insects to flowers. Any spare sugar is stored in the plant's seeds or roots.
Light is essential for plants, because they cannot make glucose without it. This is why they grow towards the light. If a plant is shut up in a dark place, it turns pale because its chlorophyll breaks down, and eventually it dies.
