So the plant has a store of energy when it can't gather enough glucose to support itself. Starch is insoluble so it can be stored within the plant easily and it can be converted back into glucose quite quickly using enzymes.
Polysaccharides are the most abundant carbohydrates. A polysaccharide molecule can contain thousands of glucose units. These highly complex carbohydrates include starches, cellulose, and glycogen. Starch is the usual form in which carbohydrates are stored as energy by plants. Plants can split starch into its simpler glucose units for use as energy when needed. Cellulose is known as a structural carbohydrate because of the fibers formed by its molecules. It is the major component of plant cell walls and comprises over half of the carbon found in plants. Humans and most animals cannot digest cellulose for food but use it as a fiber (often termed roughage) to help in the elimination of waste by the intestine.
