Why do Archaea often referred to as extremophiles because they live in conditions of extreme what?

Archaea. Means " old ones " or " ancient ones " and this is because these type of bacteria were first in the bacterial linage.

Many of the archaea are what?
Most organisms within the domain Archaea are single-celled microorganisms. These tiny organisms do not have cell nuclei that are bounded by an outer membrane. Because of this, these organisms also are called prokaryotes.
What lives 2 miles underground and eats rocks?
There is a domain of microorganisms known as "Archaea" which have been found at very great depth (up to 4 miles deep in the Earth's crust) and that metabolise the minerals in rocks. Because they are able to survive in very extreme conditions (such as the high temperatures and pressures within the Earth's crust), they are known collectively as "extremophiles". Please see the related links for more information.
Are lichens archaea?
No, because algae and archaea belong to different domains.
Why are members of this domain called archaea?
Archaea. Means " old ones " or " ancient ones " and this is because these type of bacteria were first in the bacterial linage.
Why are Archaea and different domain from bacteria?
Because some archaea are heterotrophs while others are autotrophs.
What are archae also known as extremophiles?
The archaebacteria kingdom is one of the six kingdoms. Organisms in this kingdom are also called Bacteria; they are unicellular and live in very extreme environments. The "common bacteria" belongs to another kingdom; the Eubacteria kingdom, bacteria in this kingdom differ from bacteria in the archaebacteria kingdom and they do not live in extreme environments.
What are the differences between bacteria and archeabacteria?
The main differences include:# Archaea have cell membranes composed of glycerol-ether lipids, while bacteria have glycerol-ester lipids. # Archaeal membrane lipids are also unique because the stereochemistry of the glycerol group is the reverse of that found in other organisms. # Archaea use methionine to start protein synthesis, bacteria use formylmethionine. # Archaea don't utilize chlorophyllfor photosynthesis and do not generate oxygen as byproduct of it. # Archaea are methanogenic. # As a general rule, Achaea can withstand more severe conditions than most bacteria. (ie. are extremophiles).

Archaea and eubacteria were found to be most different because?
Archaea or archaeabacteria are bacteria that are able to live in extreme conditions. They are single-celled organisms lacking a nucleus. Eubacteria have linked lipids in their cell membrane and can only survive in more normal conditions.
Can bacteria and archaea live in the same environment?
It depends. Not all bacteria and archaea can share the same environment. Most archaea are extremophiles, i.e., they live under extreme environments like high salt concentration, marshy lands, radioactive soil, etc. All bacteria however are not extremophiles. There do exist certain species who live in environments having high temperature (thermophiles), low temperature (psychrophiles), etc but most bacterial species are mesophiles and live under conditions of normal temperature (around 25 to 38 degree celsius). Moreover, temperature is not the only limiting factor. Any kind of extremity that would otherwise be lethal to most living forms are lovely places for archaea to live in. Have you ever wondered why cowdung is a good fuel source? Its because of archaea called methanogens which produce methane from the hydrocarbons present in cowdung. They are thus beneficial to us in a way!
How does earth's extremophiles help scientist research possible extraterrestrial life forms?
Because if an extremophile can survive in such harsh conditions on Earth, why cant it survive anywhere else?
Why can some bacteria live in volcanic vents?
Biota that live in extreme environments are known as extremophiles. They have evolved to like these conditions. Black Smokers in the ocean floor, are surrounded by such organisms - in that case, of ones that can survive without light and oxygen.

How are archaea helpful?
Carl Richard Woese (July 15, 1928 â?? December 30, 2012) is famous for being the one to define the archaea as a kingdom of life. His efforts to clarify the evolution and diversity of microbes proved invaluable to ecologists and conservationists. Woese's work on archaea is also significant in its implications for the search for life on other planets, as organisms similar to archaea that exist in extreme environments may have developed on other planets which harbor conditions conducive to extremophile life.
