Cell Walls of Most Archaea and Bacteria Contain Peptidoglycan

Question

Cell walls of most Archaea and bacteria contain peptidoglycan.

Accepted Answer

Most Archaea do not have cell walls containing peptidoglycan; instead, their cell walls are often composed of other polymers such as pseudopeptidoglycan. Bacteria, on the other hand, typically have cell walls that contain peptidoglycan.
