Leaves are just doing what comes naturally when they change colors and fall from trees. Find out more about this process and display your knowledge in naturally colorful way.
Autumn is a time for the beauty of the turning leaves. What causes that transformation? As the length of days and nights change (photoperiodism) and the amount of available daylight decreases, a plant’s ability to produce chlorophyll (photosynthetic pigment) is reduced. Senescence, the process of aging and death of plant part (leaf) begins to occur. Nutrients return to the stems and roots of the plant, abandoning the leaves. When the green chlorophyll is gone, yellow and orange carotinoids that have been always present are left.
Learn more about cells that form where the leaf and stem connect. After you understand the chemical processes, decide how to depict your knowledge in a three-dimensional exhibit. Here’s one way to show it.
