Answer 1

Answer #1

Both are unicellular prokaryotes & absence of nuclei so grouped into kingdom Monera.

Despite being in the same category of prokaryotes, Archaebacteria and Eubacteria show variances in their genetic makeup, as the metabolic pathways, and other enzymes, genes possessed by the archaea closely resembles eukaryotes rather bacteria.

1-Cell wall of Archaebacteria is made up of peotidoglycan , as they have ether bonds with aliphatic acid branching. Eubacterial cell wall made up of lipid membrane ester bond with fatty acid.

2- Archea do not follow the metabolic pathways like glycolysis and kreb cycle but use similar pathway, eubacteria use these pathway for energy production.
