Polysaccharides are an important class of biological polymers. Their function in living things is usually either structure or storage related.

Explanation:

Storage
Starch is used as a storage polysaccharide in plants. In animals , the structurally similar glucose polymer is the more densely branched glycogen and is sometimes called animal starch.

Structural
Chitin and cellulose are examples of structural polysaccharides. Cellulose is used in the cell walls of plants and other organisms and is said to be the most abundant organic molecule on earth.
Chitin is found in arthropod exoskeletons and in the cell walls of some fungi.
