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.

What is the greatest or largest classification group?
The largest classification group in taxonomy is Domain, which includes three main categories: Bacteria, Archaea, and Eukarya. These domains encompass all known living organisms on Earth.
What is the largest group of the classification system?
The largest group in the classification system is the domain, which includes three major groups: Bacteria, Archaea, and Eukarya. These domains encompass all living organisms on Earth and serve as the highest level of classification.
Which group includes extramophiles?
archaea
What is the largest division that a group of organisms can belong to?
The largest division that a group of organisms can belong to is called a domain. There are three domains in the classification system: Bacteria, Archaea, and Eukarya. Each domain contains multiple kingdoms, which further classify organisms into smaller groups based on shared characteristics.
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
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.
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.
What cells have prokaryotic cell structure?
Bacteria and archaea are the only types of cells that have prokaryotic cell structure. They lack a nucleus and organelles enclosed by membranes, and their genetic material is found in a single circular chromosome.
The other domain of unicellular prokaryotes?
The other domain of unicellular prokaryotes is Archaea. Archaea are a distinct group of single-celled organisms that have characteristics of both bacteria and eukaryotes. They are known for their ability to thrive in extreme environments, such as hot springs and deep-sea vents.
What is the largest group of arthropods?
Insects are the largest group of arthropods.
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.
