Choose the correct statement regarding the bacterial cell wall.

Correct option is B

The correct answer is: (b) The major component of the bacterial cell wall is peptidoglycan or murein
Explanation:
· Peptidoglycan (or murein) is the main structural component of bacterial cell walls.
· It provides rigidity and shape and protects against osmotic pressure.
· Found in both Gram-positive and Gram-negative bacteria with varying thickness.
Information Booster:
· Gram-positive bacteria: thick peptidoglycan layer.
· Gram-negative bacteria: thin peptidoglycan layer + outer membrane.
· Chitin – Found in fungal cell walls.
· Cellulose – Found in plant cell walls.
· Pectin – A polysaccharide in plant tissues, not bacteria.
· Peptidoglycan consists of sugar chains cross-linked by peptides.
Additional Information:
· Peptidoglycan is a target for antibiotics like penicillin.
· It is absent in archaea and eukaryotic cells.
