But all archaea and bacteria are not prokaryotes.

Difference between bacteria and archaea. Earlier archaea were classified as bacteria but now it s outdated as it s been found out that they both have different biochemistry and different evolutionary history. They share similar shapes. Both of them are unicellular organisms.

They do not have membrane bound organelles and nucleus. Archaea are found in the unusual environment like in hot spring ocean depth salt brines. Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids not a bilayer.

These microbes are prokaryotes meaning that they have no cell nucleus or any other membrane bound organelles in their cells. Archaea and bacteria are two kinds of microorganisms that fall under the category of prokaryotes. The archaea constitute a domain or kingdom of single celled microorganisms.

Both groups include very tiny organisms. The cell wall of archaea is pseudopeptidoglycan as they have ether bonds with the. In archaea thymine is absent in trna and introns are present whereas in bacteria thymine is absent in trna and introns are present.

Archaea have three ribosomal rna polymerase whereas bacteria have one ribosomal rna polymerase. Archaea and bacteria are microorganisms. Both bacteria and archaea have different ribosomal rnas rrna.

Bacteria constitute a large domain of prokaryotic microorganisms. What are the similarities between archaea and bacteria.
