Answer:
Archaea possess a broader range of cell envelope structural formats than eubacteria and their cell walls do not contain peptidoglycan. Some archaea have only a single S-layer as their cell wall (e.g. Methanococcus jannaschii and Sulfolobus acidocaldarius), whereas others have multiple layers (e.g. Methanospirillum hungatei). Sometimes there can also be a high proportion of tetraether lipids in membranes to make the envelope more resilient
