Which term refers to the structural polysaccharide found in many fungal cell walls and in arthropod exoskeletons?

Explanation:
Chitin is the structural polysaccharide that forms fungal cell walls and arthropod exoskeletons. It’s a long chain polymer of N-acetylglucosamine that creates a tough, protective, and rigid material, giving fungi and arthropods their structural support. This distinguishes it from cellulose, which is typical of plant cell walls; glycogen, which stores glucose for energy; and peptidoglycan, which makes up bacterial cell walls. So chitin best fits the description.
