Archaea prokaryotes are prokaryotic in nature. One of the differentiating characteristics between them is that eubacteria have what in they're cell walls

Eubacteria have cell walls made up of

chains of peptidoglycan.

Explanation:

Eubacteria have cell walls that cell wall composed of cross-linked chains of peptidoglycan. The peptidoglylcan is a polymer that combines both amino acid and sugar chains. Eubacteria have peptidoglylcan in their cell walls because it's play structural role in them , giving strength and rigidity, counteracting the osmotic pressure of the cytoplasm and also help during binary fission in reproduction.
