Peptidoglycan or murein is a special or distinctive feature of the cell wall in:
Correct answer: C. Bacteria
- A. Algae
- B. fungi
- C. Bacteria
- D. Plants
Explanation
The peptidoglycan (murein) sacculus is a unique and essential structural element in the cell wall of most bacteria. Peptidoglycan or murein is a unique large macromolecule, a polysaccharide, consisting of sugars and amino acids that form a mesh-like peptidoglycan layer outside the plasma membrane, the rigid cell wall characteristic of most bacteria.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
