WebMay 6, 2024 · Polysaccharides have several functions including structural support and storage. Some examples of polysaccharides include starch, glycogen, cellulose, and chitin. Starch is a vital form of stored glucose in plants. Vegetables and grains are good sources of starch. In animals, glucose is stored as glycogen in the liver and muscles. WebThe tubes in the tracheal system are made of a polymeric material called chitin. Insect bodies have openings, called spiracles, along the thorax and abdomen. These openings connect to the tubular network, allowing oxygen to pass into the body ( Figure ) and regulating the diffusion of CO 2 and water vapor.
