Detailed explanation-1: -The domain of unicellular prokaryotes that have cell walls that do not contain peptidoglycan is called Archaea.
Detailed explanation-2: -Answer and Explanation: The domain of unicellular prokaryotes that have cell walls containing peptidoglycan is Bacteria.
Detailed explanation-3: -They lack the peptidoglycan found in almost all prokaryotes and instead, in methanogens, contain a pseudomurein layer, which is similar to the peptidoglycan structure.
Detailed explanation-4: -Wall-Less Forms: Two groups of bacteria devoid of cell wall peptidoglycans are the Mycoplasma species, which possess a surface membrane structure, and the L-forms that arise from either Gram-positive or Gram-negative bacterial cells that have lost their ability to produce the peptidoglycan structures.
Detailed explanation-5: -Archaebacteria are known to be the oldest living organisms on earth. They belong to the kingdom Monera and are classified as bacteria because they resemble bacteria when observed under a microscope.
