Final answer:
Polysaccharides are complex carbohydrates that have hundreds or thousands of monosaccharides bonded together. They serve various functions in living organisms, such as storing energy and forming structures. Examples of polysaccharides include starch, glycogen, cellulose, and chitin.
Step-by-step explanation:
Polysaccharides are complex carbohydrates consisting of hundreds or thousands of monosaccharides bonded together. Examples of polysaccharides include starch, glycogen, cellulose, and chitin. They serve different functions in living organisms, such as energy storage or forming structures like cell walls.
Starch is a complex carbohydrate made by plants to store energy. Glycogen is a complex carbohydrate made by animals and fungi to store energy. Cellulose is a structural component of cell walls in plants and other organisms. Chitin is another structural polysaccharide found in the exoskeleton of arthropods.
