Could humans be considered extremophiles?
Humans are not typically considered extremophiles because we are not adapted to survive in extreme environments. Extremophiles are organisms that thrive in conditions such as high temperatures, acidity, or salinity which would be lethal to most other creatures. Humans generally require more moderate conditions to survive.
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, lichens are not archaea. Lichens are a symbiotic relationship between fungi and either algae or cyanobacteria. Archaea are a separate domain of single-celled microorganisms that have a different genetic makeup and are not involved in the formation of lichens.
Why are members of this domain called archaea?
Members of the domain Archaea are called archaea because they were initially mistaken for bacteria due to their small size and simple structure. When they were discovered to be a distinct group of organisms with unique characteristics, they were given the name Archaea, derived from the Greek word "archaios" meaning ancient, to reflect their ancient origins in evolutionary history.

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.

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.
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?
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 and eubacteria are most different in terms of their cell membrane structure, as archaea have unique membrane lipids, and their genetic machinery, which is more similar to eukaryotes than bacteria. These differences reflect distinct evolutionary lineages and adaptations to different environments.

Can bacteria and archaea live in the same environment?
Yes, bacteria and archaea can coexist in the same environment. They can be found in various habitats such as soil, water, and the human body where they play different roles. While they may compete for resources in some cases, they can also interact in beneficial ways such as through symbiosis or nutrient cycling.
Why are members of archaea called archaea?
Archaea. Means " old ones " or " ancient ones " and this is because these type of bacteria were first in the bacterial linage.
2 THINGS THAT MAKE ARCHIBACTERIA HARD TO STUDY?
Archaea can be hard to study because they often require unique laboratory conditions, such as extreme temperatures or pH levels. Additionally, some archaea do not grow readily in laboratory culture, making their study more challenging.
Are lichens archaea?
No, lichens are not archaea. Lichens are a symbiotic relationship between fungi and either algae or cyanobacteria. Archaea are a separate domain of single-celled microorganisms that have a different genetic makeup and are not involved in the formation of lichens.
