The leaves of some trees change color in the autumn, as the chlorophyll is not renewed in them. These trees (deciduous) go dormant during the winter.

As plants receive less sunlight, they change color. They are green because they have a lot of sunlight and are able to produce glucose and other energy chemicals. The less sunlight they receive, the less chemicals they produce.
Is leaves turning color in the fall a chemical or physical change?
I don't know the scientific equation, but I do know that the tree withdraws it's sugars from the leaves, during the autumn and winter to make sure that there is enough for the main tree. The withdrawal of the sugars is a physical action, but it is a chemical one as well. The chlorophyll that was made thru the sunlight on the leaves for photosynthesis. This stops when the weather turns colder and there is less sunlight causing the leaves lessen the amount to chlorophyll they can make, signaling to the tree to cut off the sugar supply to the leaves. I'd say it's both. Also, You have witnessed a spectacular chemical change if you have seen the leaves on a tree change from green to bright yellow, red, or orange. But, it is not a change from a green pigment to a red pigment, as you might think. Pigments are chemicals that give leaves their color. In autumn, however, changes in temperature and rainfall amounts cause trees to stop producing chlorophyll. The chlorophyll already in the leaves undergoes a chemical change into colorless chemicals.Where do the bright fall colors come from? The pigments that produce fall colors have been present in the leaves all along. However, in the summer, chlorophyll is present in large enough amounts to mask these pigments. In the fall, when chlorophyll production stops, the bright pigments become visible.
