Leaves are lovely
Leaves add beauty to the nature and it gives oxygen to all human being.
Why do leaves change colors?
Chlorophyll is the chemical in leaves that make them green in color. In spring and summer, when there is lots of sunlight, this chemical absorbs energy from the sun and turns it into carbon dioxide and water into sugar and starch.
However, during the fall and winter when there isn’t much sunlight the leaves stop making food and the chlorophyll breaks down making the green color disappear. The other color of the leaves begin to show such as red, orange, yellow and gold. As the leaf is changing colors, the stem is also changing.
Where it is attached at the tree (leaf axil) the cells supporting the leaf are cut. When the wind blows or if the stem is dry, the leaf falls to the ground. That’s why the trees become bare in autumn! Trees that lose there leaves after changing color are called deciduous trees for example oak, maple, birch and elm.
