Domain Bacteria And Domain Archaea Similarities

Archaea is a group of primitive prokaryotes that based on their distinct characteristics form a separate domain from bacteria and eukaryotes.

Domain bacteria and domain archaea similarities. They can be autotrophs or heterotrophs. The archaea are the separate domain of life in prokaryotes. The evolutionary history led to the difference in classifying archaea with bacteria.

They mainly reproduce in a binary fission. Video explaining the differences. Archaea is another domain of single celled microbes that was in the past classified under bacteria blainey 2013.

However archaea and bacteria share a lot of similarities as well. Archaea have a diverse. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.

The cells split in two like bacteria. They are both prokaryotes without any complex cell structure like eukaryotes. The general cell structure of archaea and bacteria are the same but composition and organization of some structures differ in archaea.

On the tree of life cells of the domain archaea are situated between the cells of bacteria and those of the eukarya which include multicellular organisms and higher animals. Both distinguish almost identical looks when looking through a microscope since they are both prokaryotes. Archaea and bacteria both have 70s ribosome but bacterial ribosome is sensitive to certain chemicals which act as inhibiting agents while archaea are insensitive to these chemicals like that of the eukaryotes.

But they are definitely not bacteria even though archaea and bacteria share some similarities. Bacteria are usually present in every habitat and other living organisms. Archaea reproduce asexually through binary fission.
