Answer:

Polysaccharides, one of the carbohydrate classes, act as structural and supporting elements in plant and bacterial cell walls and also in connective tissue and animal cell lining. They also act as the reserve of energy producing monosaccharides. Reserve homopolysaccharides in plant cells are starch and in animal cells glycogen.

The main functions of structural polysaccharides in animals are the stabilization and support of cellular and fibrous tissue components, conferring resistance while helping to maintain the water and ionic balance.
