Peptidoglycan or murein is a special or distinctive feature of cell wall in:
Correct answer: C. Bacteria
- A. Algae
- B. Fungi
- C. Bacteria
- D. Plants
Explanation
The correct answer is Bacteria because their cell walls are composed of peptidoglycan, a unique polymer that provides structural integrity and protection. This is a distinctive feature of bacterial cell walls. In contrast, algae and plants have cell walls made of cellulose, while fungi have cell walls composed of chitin. These differences in cell wall composition are key characteristics that distinguish these groups of organisms.
