Most archaea (but not Thermoplasma and Ferroplasma) possess a cell wall. In most archaea the wall is assembled from surface-layer proteins, which form an S-layer. … Unlike bacteria, archaea lack peptidoglycan in their cell walls.

Is cell wall present in archaebacteria?

Archaea are single-celled microorganisms that lack a cell nucleus and membrane -bound organelles. Like other living organisms, archaea have a semi-rigid cell wall that protects them from the environment.

Is there a cell wall in eubacteria?

Eubacteria -as well as archaebacteria- are prokaryotes. Prokaryotic Eubacteria includes bacteria with cell walls consisting of peptidoglycan. However, not all bacteria have cell walls. But all eubacteria have a cell membrane.

Archaea are completely Non-Pathogens while eubacteria have both pathogenic and non-pathogenic bacteria. The cell wall of Archaea is made up of Pseudopeptidoglycan as they also have ether bonds with aliphatic acid while eubacteria have a lipid membrane ester links with fatty acids.
