what are three names of polysaccharides and their function in cells
Starch and glycogen serve as short-term energy stores in plants and animals, respectively. Cellulose is the main component of plant cell walls.
how is cellulose different from starch and glycogen?
The glucose units in cellulose are linked by β glycosidic bonds, different than the α glycosidic bonds found in glycogen and starch.
any other differences in cellulose from starch and glycogen?

what are examples of cellulose?
Wood, paper, and cotton are the most common forms of cellulose.
