The Fungal Cell wall contains:
Correct answer: B. Chitin
- A. Peptidoglycan
- B. Chitin
- C. Suberin
- D. Cutin
- E. Proteins
Explanation
Option A: Peptidoglycan: A type of polysaccharide found in the cell walls of bacteria and some archaea. Made up of repeating units of N-acetylglucosamine and N-acetylmuramic acid, which are linked together by peptide bonds. Option B: Chitin: A polysaccharide made up of repeating units of N-acetylglucosamine, which are linked together by beta-1,4 glycosidic bonds. Provides the cell wall with its strength and rigidity. Option C: Suberin: A type of waxy substance found in the cell walls of plants. Option D: Cutin: A type of fatty substance found in the outer layer of plant cell walls. Option E: Proteins are found in all cell walls, and they play a variety of roles, such as providing structure, anchoring the cell wall to other structures, and interacting with the environment.
