Fallen Leaves

October 2005
Scholastic Parent & Child;Oct2005, Vol. 13 Issue 2, p12
The article presents information on the biochemistry of leaves. Leaves use water, sunlight, carbon dioxide and chlorophyll. This process is called photosynthesis. Chlorophyll is what makes leaves green in spring and summer. Leaves also have yellow and orange in them, but the green chlorophyll hides these other colors. During winters, the chlorophyll which the leaves had been using to make food for the tree disappears. When it's gone, one can see the orange, yellow and other colors that had been covered by green.
