Archaea (/ ɑːr ˈ k iː ə / ⓘ ar-KEE-ə) is a domain of organisms.Traditionally, Archaea only included its prokaryotic members, but since this has been found to be paraphyletic, as eukaryotes are now known to have evolved from archaea. Even though the domain Archaea cladistically includes eukaryotes, the term "archaea" (sg.: archaeon / ɑːr ˈ k iː ɒ n / ar-KEE-on, from the Greek ...

4 天之前 · Archaea are microorganisms that define the limits of life on Earth. They were originally discovered and described in extreme environments, such as hydrothermal vents and terrestrial hot springs. They were also found in a diverse range of …

2022年12月16日 · Archaea are a domain of single-celled microorganisms. They are extremophiles, capable of surviving in extreme environments where no other organisms would survive. The domain Archaea...

2023年10月19日 · Archaea, formerly known as ‘archaebacteria,’ are a group of single-celled, prokaryotic organisms belonging to the domain Archaea. Apart from Archaea, Bacteria and Eukarya are the other two domains of life that currently exist.

2022年1月24日 · Archaea are single-celled organisms that are similar to bacteria, though they have different characteristics. They can be spherical, rod-shaped, spiral, or rectangular. Beyond the human body,...

2023年10月8日 · Archaea is a domain of life, together with Bacteria and Eukarya, containing single-celled prokaryotes other than bacteria. They are the oldest life-form known to exist. The name Archaea is derived from the Greek word ‘ARCHAIOS’ meaning primitive.

In this paper, we discuss human diseases in which archaea may play a role as well as potential virulence characteristics of archaea, possible explanations for the current absence of information about archaea as pathogens, and molecular methods that might be …

archaea, A group of prokaryotes whose members differ from bacteria, the most prominent prokaryotes, in certain physical, physiological, and genetic features. The archaea may be aquatic or terrestrial microorganisms. They exhibit a diversity of …

Archaeans include inhabitants of some of the most extreme environments on the planet. Some live near rift vents in the deep sea at temperatures well over 100 degrees Centigrade. Others live in hot springs (such as the ones pictured above), or in extremely alkaline or acid waters.

Archaea are unicellular prokaryotes that comprise the domain of the same name, Archaea. These microorganisms physically resemble the bacteria but are genetically distinct from the latter. Archaea are typically found inhabiting and thriving in extreme environmental conditions.
