what is the difference between the kingdoms archaea and bacteria?
203861
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.

Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles. They are tiny, single-cell organisms which cannot be seen by the naked human eye called microbes.

While both archaebacteria and eubacteria are prokaryotic, they are evolutionarily different. All prokaryotic cells are unicellular, have a cell wall and lack both a nucleus and membrane-bound organelles. ... The domain bacteria contains the kingdom eubacteria and is known as true bacteria.

But it was discovered that archaea have a distinct evolutionary history and biochemistry compared with bacteria. The similarities are that archaea and eubacteria are prokaryotes — single-celled organisms that do not have a nucleus or organelles.

Life on earth is classified into three domains: Bacteria, Archaea and Eukarya. The first two consist completely of single-celled microbes. None of them have a nucleus. The third domain, Eukarya, consists of organisms whose cells have a nucleus.

A difference between all three domains is what their cell walls contain. A cell wall in domain Archaea has peptidoglycan. The organisms that have a cell wall in domain Eukarya, will have a cell wall made up of polysaccharides. A cell wall in domain Bacteria contains neither peptidoglycan or polysaccharides [13b].

The primary difference between them is their cellular organization. Bacteria are single-celled microbes and are prokaryotes, which means they're single-celled organisms lacking specialized organelles. ... In contrast, protists are mostly single-celled eukaryotic organisms that are not plants, fungi, or animals.

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.

Although these two types of bacteria are extremely small, the differences are very significant: eubacteria is very ubiquitous these days and can be found everywhere, while archaebacteria can only be found in certain conditions.

Protozoa are eukaryotic organisms while bacteria are prokaryotic organisms. Protozoa do not have cell walls while bacteria have cell walls. Bacteria have either heterotrophic mode of nutrition or autotrophic mode of nutrition while protozoa have only heterotrophic mode of nutrition.

Yeast is a eukaryotic organism while bacteria are prokaryotes. Both yeast and bacteria are unicellular organisms with a cell wall. Yeast contains a nucleus and membrane-bound organelles but, bacteria lack a nucleus or membrane-bound organelles.

Bacteria have a unique compound called peptidoglycan in cell walls. Archaea have unique phospholipids in their plasma membrane and hydrocarbon tails that contain isoprene.
881728
These relationships indicate that archaea are more closely related to eukaryotes than to bacteria, even though superficially archaea appear to be much more similar to bacteria than eukaryotes.
1443637
Like bacteria, organisms in domain Archaea are prokaryotic and unicellular. Superficially, they look a lot like bacteria, and many biologists confused them as bacteria until a few decades ago.

Similarities Between Them Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles. They are tiny, single-cell organisms which cannot be seen by the naked human eye called microbes.

In time, the prokaryotes of the kingdom Monera were separated into the kingdom Archaea and the kingdom Bacteria. The kingdom Animalia consists of multicellular, eukaryotic organisms. The eukaryotic cells that make up these individuals have a membrane-bound nucleus and other membrane-bound organelles.

The two types of organisms differ in their cellular structures in that the cell wall of Bacteria contains the molecule peptidoglycan, while that of Archaebacteria does not. In addition, the lipid membranes of the two also contain different molecules.
