Answer :

Final answer:

Gram-positive bacterial cell walls are mainly composed of peptidoglycan, providing strength to the cell.


Explanation:

Gram-positive bacterial cell walls are primarily composed of peptidoglycan, which can make up to 90% of the cell wall. This polymer consists of N-acetylglucosamine linked to N-acetylmuramic acid and peptide units, creating a strong structure around the cell membrane.
