The difference between the Archaea and Eubacteria is that Archaea is a single-celled bacterium that thrives in extreme conditions while eubacteria live and thrive in normal conditions. Archaea is the oldest bacteria ever known while the earth was formed. Both Archaea and Eubacteria belong to the kingdom called Monera.

What is the main difference between eubacteria and archaebacteria?
Eubacteria are usually found in soil, water, living in and on of large organisms. Eubacteria are divided into two groups known as gram positive and gram negative bacteria. Archaebacteria are found in salt brines, ocean depths and hot springs. They have evolved just after the evolution of first life on earth.
What are 3 differences between bacteria and archaea?
Differences between bacteria and archaea include the presence of peptidoglycan in bacteria's cell walls, differing numbers of ribosomal RNA polymerases, archaea's adaptability to extreme conditions, and bacteria's aversion to antibiotics.
What is the difference between eubacteria and archaebacteria quizlet?
Archaebacteria are extremophiles while eubacteria are not. ... Archaebacteria's cell wall is not composed of peptidoglycan, but of other types of polysaccarides. Eubacteria are made of peptidoglycan.
What are the differences between bacteria and archaea?
Archea have three RNA polymerases like eukaryotes, but bacteria have only one. ... Archaea have cell walls that lack peptidoglycan and have membranes that enclose lipids with hydrocarbons rather than fatty acids (not a bilayer).
What are 2 examples of archaebacteria?
Archaebacteria are primitive, single-celled microorganisms that are prokaryotes with no cell nucleus.
- Acidilobus saccharovorans.
- Aeropyrum pernix.
- Desulfurococcus kamchatkensis.
- Hyperthermus butylicus.
- Igniococcus hospitalis.
- Ignisphaera aggregans.
- Pyrolobus fumarii.
- Staphylothermus hellenicus.
What are the similarities and differences between bacteria and archaea?
Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. 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.
What are the 3 main domains of life?
According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. The first two are all prokaryotic microorganisms, or mostly single-celled organisms whose cells have no nucleus.
Why Archaea and Bacteria are classified separately?
This Archaea domain contains single-celled organisms. Archaea have genes that are similar to both bacteria and eukaryotes. Because they are very similar to bacteria in appearance, they were originally mistaken for bacteria. ... These differences are substantial enough to warrant that archaea have a separate domain.
Are Archaea older than bacteria?
And it is no longer believed that Archaea are any older than Bacteria, as their name and the New York Times headline might imply. ... Now, probably all textbooks show Life as comprising the domains Bacteria, Archaea and Eukarya, with the last two the more closely related.
Why are archaebacteria and eubacteria in different kingdoms?
There are two kingdoms of prokaryotes. These are the bacteria (or eubacteria ) and the archaebacteria (or the Archaea ). ... It is these differences that have resulted in the microorganisms being grouped into separate kingdoms. For example, eubacteria contain the rigid, stress-bearing network known as the peptidoglycan .
What is the difference in the structure of the enzyme RNA polymerase between eubacteria and archaebacteria?
In archaea features like thymine is absent in the tRNA (transferase RNA) and introns are present, whereas in bacteria thymine is present in the tRNA and introns are absent. In archaea, the RNA polymerase is complex and contains ten subunits, while in RNA polymerase in bacteria is simple and contains four subunits.
