Leaves don’t seem to do anything at all. But if you could become tiny enough to peek inside a leaf – you would have a surprise!
Sunlight comes into a leaf through the leaf’s skin. Inside, the leaves have a wonderful green substance called chlorophyll. The chlorophyll catches some of the sunlight that falls on the leaf. At the same time, air comes into the leaf through many tiny openings. And water moves up from the roots below.
Leaves are like little food factories. Using sunlight for energy, the chlorophyll changes water and a gas from the air into food for the plant.
Besides green, leaves have other colours, such as yellow and orange. In summer, the green chlorophyll covers the other colours. In the autumn, it sometimes fades. Then you see the other colours.
