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 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 group thrives in extreme heat and acidic environments?
Thermophiles, which are organisms that thrive in extreme heat, and acidophiles, which are organisms that thrive in acidic environments, are known to adapt and thrive in such conditions. These extremophiles have unique adaptations that allow them to survive and even thrive in environments that would be inhospitable to most other life forms.
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?
Archaea. They are a group of single-celled microorganisms that have unique cell membranes and thrive in extreme environments like hot springs, salt flats, and deep-sea hydrothermal vents. They are distinct from bacteria and eukaryotes in their genetic makeup and cell structure.
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.
How many domains do scientist group living things into?
Scientists group living things into three domains: Bacteria, Archaea, and Eukarya. This classification system is based on differences in cellular structure and genetic makeup. Each domain contains multiple kingdoms that further categorize different types of organisms.
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 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.
