Detailed explanation-1: -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-2: -Like bacteria, archaea have rigid cell walls. However, unlike bacteria, archaea lack peptidoglycan.

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. In general, archaeal structures have been studied in less detail than the corresponding bacterial structures.

Detailed explanation-4: -The cell walls of gram positive bacteria are composed predominantly of peptidoglycan.
