What structural polysaccharide forms the rigid cell walls of fungal organisms?
Answer and explanation
Correct answer: B. Chitin
- Step 1: Different biological kingdoms use distinct structural carbohydrates for their cell envelopes.
- Step 2: Fungal cell walls are composed of chitin, a tough polymer of N-acetylglucosamine units (also found in arthropod exoskeletons).
Answer
Chitin.
Why not the others: 'Cellulose' forms plant cell walls; 'Peptidoglycan' forms bacterial cell walls; 'Glycogen' is an energy storage polysaccharide in animals and fungi.
