Question: what is the difference between archaea and bacteria cell walls?
Answer: Bacteria and Archaea differ in the lipid composition of their cell membranes and the characteristics of the cell wall. ... Bacterial cell walls contain peptidoglycan. Archaean cell walls do not have peptidoglycan, but they may have pseudopeptidoglycan, polysaccharides, glycoproteins, or protein-based cell walls.
