Disappearing Green
Different natural chemicals within trees produce different colours of leaves. Chlorophyll is the chemical that produces a green colour, and it happens that photosynthesis (the process of turning sunlight into energy, which is key to tree growth) is most efficiently processed with green leaves.
Dispensing With Leaves
In the spring, a layer of cells called the abscission layer is formed where a leaf grows out from a branch. During the growing season, the tree hormones and chemicals are fairly steady, and this layer allows energy from the leaves to be passed into the branch and trunk to be stored.
Conifers
So why do some trees not shed leaves or change colour at all? Conifer trees are a little different. Many conifers have needles rather than leaves. These needles are often heavily impregnated with a resin which resists cold and wet weather far better than a frail leaf.
