The prokaryotic cell wall is composed of:
Correct answer: C. Murein
- A. Cellulose
- B. Chitin
- C. Murein
- D. Pectin
Explanation
Option C is correct.The prokaryotic cell wall is composed of murein, also known as peptidoglycan. Murein is a polymer made up of two sugar molecules and a short peptide chain. It is a very strong and rigid material that helps to protect the cell from osmotic lysis and other environmental stresses.Cellulose is a polymer of glucose molecules that is found in the cell walls of plants. Chitin is a polymer of N-acetylglucosamine molecules that is found in the exoskeletons of insects and other invertebrates. Pectin is a polymer of galacturonic acid molecules that is found in the cell walls of plants.

About Prokaryotic and Eukaryotic Cells
Prokaryotic cells lack a membrane-bound nucleus and complex membrane-bound organelles, whereas eukaryotic cells contain a nucleus, specialized organelles and a cytoskeleton. Comparisons include DNA organization, ribosomes, cell walls, size, division and examples such as bacteria, archaea, protists, fungi, plants and animals.
