Exoskeleton of arthropods is composed of:
Answer: (C) Chitin. Answer: (C) Chitin.
- A.Cutin
- B.Cellulose
- C.Chitin✓
- D.Glucosamine
Correct Answer
(C) Chitin
Solution & Explanation
Answer: (C) Chitin. Solution: The exoskeleton of arthropods is built from a complex structural polysaccharide. NCERT states directly that exoskeletons of arthropods have a complex polysaccharide called chitin. Cellulose is the plant cell wall polysaccharide and glucosamine is only one of the modified amino-sugar building blocks, so chitin is the correct answer. NCERT Reference: Ch 9, p.111, line ~7 — "Exoskeletons of arthropods, for example, have a complex polysaccharide called chitin."
