Solution:
Polysaccharides are complex long chain carbohydrates which are formed by dehydrate synthesis or polymerisation of more then 10 but generally very large number of units called monosacccharides. Starch, glycogen
and cellulose are all polysaccharides. Starch is a glucosan homopolysaccharide which is the main reserve food of plants. Glycogen is also a glucosan homopoly- saccharide which is the major reserve food of fiingi,
animals and some bacteria. It is also called animal starch. Cellulose is the structural polysaccharide of plant cell walls, some fungi, protists. It is a fibrous glucosan homopolysaccharide of high tensile strength.
