Answer:
have cell walls composed of substances other than peptidoglycan
Explanation:
Archaea are single celled microbes with the absence of cell nucleus and cell membrane-bound organelles just like bacteria. Archaea and bacteria both reproduce by binary fission. As it relates to their gene structure, they both have a circular chromosome.
Compared to bacteria, archaea lack peptidoglycan in their cell wall, but contain psuedo-peptidoglycan that is similar to peptidoglycan in physical structure and function, but not in chemical structure.
