Detailed explanation-1: -How are they different from bacteria? 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.
Detailed explanation-2: -Prokaryotes, which include both bacteria and archaea, are found almost everywhere – in every ecosystem, on every surface of our homes, and inside of our bodies! Some live in environments too extreme for other organisms, such as hot vents on the ocean floor.
Detailed explanation-3: -Both bacteria and archaea have cell membranes and they both contain a hydrophobic portion. In the case of bacteria, it is a fatty acid; in the case of archaea, it is a hydrocarbon (phytanyl). Both bacteria and archaea have a cell wall that protects them.
Detailed explanation-4: -All of life can be divided into three domains, based on the type of cell of the organism: Bacteria: cells do not contain a nucleus. Archaea: cells do not contain a nucleus; they have a different cell wall from bacteria.
Detailed explanation-5: -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.
