Differences Between Archaea and Bacteria

3D Model

Archaea and Bacteria are two kinds of microorganisms that fall under the category of prokaryotes. Earlier, archaea were classified as bacteria, but now it is outdated as it has been found that they both have different biochemistry and different evolutionary history.
Archea is a domain of living organisms containing unicellular prokaryotic organisms. Cell wall in arechea is made up of Pseudopeptidoglycan, whereas in bacteria, it is made up of either Lipopolysaccharide or Peptidoglycan.
