Solution
The correct option is D Cellulose
Glucan is the polysaccharide of glucose and cellulose is a fibrous homopolysaccharide. Cellulose molecules have linear chains. It is made up of glucose residues and joined by 1-4 beta linkage. Starch and Glycogen are food storage polysaccharides. They are also a made up of glucose residues but have highly branched structure. Starch is present in plants and glycogen in animals is the equivalent of starch in plants. Thus, the correct option is A.
