Poly saccharides are carbohydrates, supporting tissues of plants and are important foods for animals and humans
Two examples of polysaccahrides are cellulose (makes up plant cell walls) and glycogen (which is how carbohydrate is stored in the cells of the body).
STARCH in plants. GLYCOGEN in animals.
