Which polysaccharide forms the exoskeleton of insects and the cell walls of fungi?
Correct answer: D. Chitin
- A. Cellulose
- B. Glycogen
- C. Pectin
- D. Chitin
Explanation
Chitin is a tough nitrogen-containing polysaccharide that builds arthropod exoskeletons and fungal walls. Cellulose is the structural polymer of plant walls, and glycogen is an animal storage polysaccharide, so each structural role maps to its own polysaccharide.

About Classification of Biological Molecules
Biological molecules are classified as carbohydrates, lipids, proteins and nucleic acids, with water, minerals and vitamins also supporting cellular processes. The key distinctions involve their monomers, chemical bonds, structures and functions, including glucose and starch, fatty acids and triglycerides, amino acids and polypeptides, and nucleotides in DNA and RNA.
