How do the cell walls of the Archaea compare to the cell walls found in Bacteria?

Cell walls in Archaea are composed of ester-linked hydrocarbons, while those in Bacteria are made of ether-linked fatty acids.
Cell walls in Bacteria are made of peptidoglycan, while those in Archaea are not.
Cell walls in Archaea are made of peptidoglycan, while those in Bacteria are made of cellulose or chitin.
Cell walls in Archaea are thinner and more flexible than those found in Bacteria.

Cell walls in Bacteria are made of peptidoglycan, while those in Archaea are not.

Explanation:

Both Arachea and Bacteria are prokaryotes but the composition and features of their cell walls are different.

The bacterial cell wall consists of a polysaccharide called peptidoglycan. This is a strong polysaccharide chain linked

with peptides (L- and D- amino acids). ). The antibiotics that are given to treat bacterial infections act mainly to destroy these peptide links of the bacterial cell wall. Depending upon the type of bacteria, there are many forms of peptidoglycans.

The arachea cell wall does not contain peptidoglycan; however, it has pseudo-peptidoglycan. Pseudo-peptidoglycan is similar to that of peptidoglycan, but their polysaccharide chains differ.

Aracheans also can have protein, polysaccharide or glycoprotein-based cell walls other than pseudo-peptidoglycan

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
