During the spring and summer, leaves serve as factories where most of the food necessary for the tree's growth are manufactured. This food-making process takes place in the leaf in numerous cells containing chlorophyll, which gives the leaf its green color. Along with the green pigment are yellow to orange pigments, carotenes and xanthophyll pigments. Most of the year these colors are masked by great amounts of green coloring. But in the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears and the yellow and orange colors become visible.

Leaves are the food factories of plants. During the spring and summer, they are actively making food and are filled with pigments, like chlorophyll, which gives the leaves their green color. As summer ends and the days get shorter and cooler, food production stops and the leaves stop producing food. The chlorophyll disappears but other pigments that are also present in the leaf, but were masked by chlorophyll, start to appear, like anthocyanins of betaxantins. This gives leaves unique color every autumn.

Each bud on a tree is the beginning of a new leaf. The sun warms the bud and the new leaf begins to grow. As the leaf grows it starts to make its own food.


Each leaf is like a tiny food factory. The leaf uses sunlight, things in the air, water and a green matter called CHLOROPHYLL. (CHLOR-RO-FILL)The green chlorophyll covers up the other colors of the leaf. It covers up the other colors so we can see only green leaves.

When fall begins, the leaf starts to die. There is less sunlight because the days are shorter. The leaf no longer makes food.


When the leaf begins to die, the leaf no longer makes food. The chlorophyll breaks down and the green color begins to disappear.


All the hidden colors--the reds, yellows, Oranges, and browns can now be seen!

What organelle is responsible for the reds oranges and yellows in autumn leaves?

Four pigments in leaves, chlorophyll, carotenoids, anthocyanins and tannins are responsible for leaf color changes. Cartenoids are responsible for the yellow and orange pigments of leaves. They reside in the chloroplasts and assist chlorophyll in the photosynthesis process. As chlorophyll diminishes, the color changes. Anthocyanins cause leaves to turn to red. It is formed in the cell sap that resides inside the vacuole.
