Comparison with Other Substances

When considering the options provided:

• Cellulose: A polysaccharide found in plant cell walls, primarily composed of glucose units.
• Chitin: A structural component in the exoskeletons of arthropods and the cell walls of fungi, made of N-acetylglucosamine.
• Cuticle: A protective layer found in plants and animals, but not a polysaccharide.
• Scleroprotein: A type of protein that provides structural support, such as collagen in animals.
