Nature’s colors are in full display during the Fall season. Plants have an ingenious way of self-preservation during the cooler months of the year. This is noticeable as the trees shed their leaves and the branches are left bare in the winter.

A lot of the change of color has to do with the weather. In the fall the amount of cool weather that the plants receive and the reduced amount of sunlight contribute to the break down in the chloroplast in the leaves. Chloroplast is what makes leaves green, therefore when the leaves are no longer green that means that the plant, or leaf, is no longer producing glucose, which is also known as sugar. The chloroplast converts energy from the sun that can be used to make sugars that the plant cells need to grow. Due to temperature drop we get less sun and without sunlight the plant cannot make glucose so the leaves start to die and fall off the tree.
