Glucose is a kind of sugar that plants use as food for energy and for growing.

Once they’d know that it’s time to get ready for winter they began to shut down their food making processes and the green chlorophyll disappears from the leaves. As the bright green of the leaves begins to fade away we begin to see the yellowish and orange colors as small amounts of these colors have typically been in the leaves all along although we just can’t see them in the summertime because they are covered up by the green chlorophyll.

In the fall we also see bright reds and purples which are mostly made in the fall time. In some trees says and maples glucose is trapped in the leaves after the photosynthesis process stops. The cool nights of law am in addition to sunlight cause the leaves to turn this glucose into a red color. The brown coloring of trees like opuses made from the wastes left in the leaves.
