Like bacteria, Archaea are single-celled organisms lacking nuclei. Most are cocci, bacilli, or spiral forms (although unusual shapes do exist). Unlike bacteria, Archaea lack peptidoglycan in their cell wall. At this point Archaea are not known to cause disease in humans or animals.
Members of the kingdom Archaea had been considered to be bacteria until examination of their unique rRNA sequences showed that they are a distinct type of prokaryote. And despite being prokaryotes, Archaea appear to be more closely related to Eukaryotes than to Bacteria.
This is the largest group of Archaea. Methanogens derive their name from the fact that methane is one of their metabolic byproducts.
The largest group of Archaea is methanogens.

Which group includes extramophiles?
archaea
What cells have prokaryotic cell structure?
Bacteria and archaea. Archaea is a group of micro-organisms.
What group thrives in extreme heat and acidic environments?
Archaea
What prokaroytic group inhabits extreme environments?
The prokaryotic group that tend to inhabit extreme environment belongs to the domain archaea. Prokaryotes reproduce by means of binary fission.
What is the broadest taxonomic group?
The DOMAIN of a species is the largest group of classification. (From broadest group to actual species): Domain Kingdom Phylum Class Order Family Genus Species
Diseases caused by archaea?
Archaea are a group of single-celled microorganisms. There are no cases of confirmed diseases having been caused by archaea, yet this does not mean that they are not capable of causing disease.
What is an detail about domain archaea?
A group of microorganisms that resemble bacteria but are different from them such as the composition of their cell walls. Archaea usually live in extreme, often very hot or salty environments. The archaea are considered a separate kingdom in some classifications. Some scientists believe that archaea were the earliest forms of cellular life.
A group of prokaryotes that often live in extreme environments is the?
extremophiles. Usually, they're archaea.
How many domains do scientist group living things into?
There are three domains: eubacteria, archaea, and eukaryota.
What is one difference between domain eukarya and domains bacteria and archaea?
Archaea and bacteria are both prokaryotic and have a cell wall. Eukarya is the largest and is thought to have evolved from prokaryotic. All three organisms are the building blocks of life.
What is on major difference between domain Eukarya and domain Bacteria and Archaea?
Archaea and bacteria are both prokaryotic and have a cell wall. Eukarya is the largest and is thought to have evolved from prokaryotic. All three organisms are the building blocks of life.
What is the largest group of arthropods?
Insects are the largest group of arthropods.
