Prokaryotic organisms are split between the two domains Arch

Prokaryotic organisms are split between the two domains, Archaea and Bacteria. Why was it necessary to put these organisms in two different domains? Archaean ribosomal RNA is more like the ribosomal RNA of eukaryotes than of bacteria. The cell walls of archaea have no peptidoglycan, which is present in the cell walls of all bacteria. Several aspects of protein synthesis in archaea are different from bacterial protein synthesis. Some archaea have a nuclear membrane surrounding the DNA whereas bacteria do not. Archaea are found living in extremely salty environments that bacteria cannot tolerate.

Solution

Archae and bacteria have one thing in common and that is they do not have a nuclear membrane unlike eukaryotes.

Bacterial cell walls are made up of peptidoglycans containing murein. Archae do not contain murein so their cell wall is different from bacterial cell wall.

Archae are also found living in extreme conditions which bacterial cells are not able to tolerate.
