During spring and summer when there is plenty of sunlight, plants make a lot of chlorophyll. As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall. In fall, plants break down and reabsorb chlorophyll, letting the colors of other pigments show through.

Then, why do leaves turn red?

The short answer is that leaves fall off trees when they aren't doing their job any more. A leaf's job is to turn sunlight into food for the tree. To do this, the leaf needs water. The tree doesn't want to waste all the good things in the leaf, so it takes the nutrients from the leaf back into the stems and roots.

What happens to trees in autumn?

During the growing season, trees create chlorophyll as fast as they use it up, so leaves stay green. And autumn leaves.
