The peptidoglycan cell wall is specific to:
Correct answer: B. Bacteria
- A. Amoeba
- B. Bacteria
- C. Protozoa
- D. Virus
Explanation
Peptidoglycan is a complex polymer found in the cell walls of bacteria. It provides structural strength, rigidity, and shape to the cell wall and protects the cell from osmotic lysis. Peptidoglycan is composed of sugar chains cross-linked by short peptide chains, forming a strong, mesh-like structure. This structure is crucial for bacterial survival, especially in Gram-positive bacteria, where peptidoglycan is particularly thick.
