Final answer:
Polysaccharides are complex carbohydrates that consist of hundreds or even thousands of monosaccharides. They include starch, glycogen, cellulose, and chitin. These carbohydrates serve either as energy storage or structural components in living things.
Step-by-step explanation:
Polysaccharides are complex carbohydrates that consist of hundreds or even thousands of monosaccharides.
They include starch, glycogen, cellulose, and chitin. Starch, found in plants, is used to store energy.
Glycogen, produced by animals and fungi, plays a critical role in regulating blood glucose levels.
Cellulose forms the structural component of plants, while chitin is found in the exoskeleton of insects.
