Autumn golden

Why do leaves change color. The green color of the leaves in plants is due to the fact that their cells contain such a pigment as chlorophyll. It absorbs sunlight and synthesizes nutrients for plant life to function.
The nutrients accumulated in the leaves throughout the summer begin to move to the root, trunk and branches, where they remain during the cold weather. When it gets warm, they will be used to grow new leaves, cycle after cycle. After the leaves have parted with all the beneficial substances, there will no longer be any point in chlorophyll. It will be replaced by pigments of a completely different color, which will give the foliage a special, autumn coloring.
The yellow pigment that replaces chlorophyll in the leaves of some trees, such as hazel or birch, consists of carotene, the very pigment responsible for the orange color of carrots.
