Why do leaves change color in the fall?
As plants receive less and less sunlight in the shortened days of fall, the production of chlorophyll, a substance which makes the leaves appear green by saturating them through turning sunlight into glucose, slows down. Without chlorophyll, the "true" color of leaves comes through, according to the Smoky Mountains website.
Changed leaves then begin to fall off their trees as the trees close off their veins in preparation for protection in winter, meaning the leaves no longer receive nutrients and therefore weaken at the stem.
