We all enjoy the colors of autumn leaves. Did you ever wonder how and why a leaf changes color in the Fall?
Plants make their own food. They take water from the ground through their roots and a gas from the air called carbon dioxide. They turn water and carbon dioxide into food and oxygen. Plants make their food using sunlight and something called chlorophyll. Chlorophyll gives leaves their green color. Many plants stop making food in the fall and the chlorophyll goes away. Then we can see the orange and yellow colors. These colors were in the leaves all summer, but the green covered them up. The red color in fall leaves is caused by food trapped in the leaves and the brown color comes from wastes left in the leaves.
So go outside and enjoy a walk on the Greenbelt and the beauty of the autumn leaves.
