Is glycogen in wood and cotton?

Glycogen is not found in wood or cotton. Glycogen is a polysaccharide that serves as a form of energy storage primarily in animals and fungi. Wood and cotton, on the other hand, are primarily composed of cellulose, which is a structural polysaccharide found in the cell walls of plants. While both glycogen and cellulose are carbohydrates, they serve different functions and are present in different types of organisms.
