The halophiles, named after the Greek word for "salt-loving", are extremophiles that thrive in high salt concentrations. While most halophiles are classified into the domain Archaea, there are also bacterial halophiles and some eukaryotic species, such as the alga Dunaliella salina and fungus Wallemia ichthyophaga.

Which of these organisms has the best potential to survive in extreme environments?
Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.
What is true of Archaea?
Archaea are unicellular, prokaryotic microorganisms that differ from bacteria in their genetics, biochemistry, and ecology. Some archaea are extremophiles, living in environments with extremely high or low temperatures, or extreme salinity. Only archaea are known to produce methane.
Is the specific process by which microbes carry out the decomposition of harmful chemicals?
Indeed, biodegradation is the process by which organic substances are broken down into smaller compounds by living microbial organisms [2]. When biodegradation is complete, the process is called "mineralization".
How do organisms live in extreme environments?
Extremophiles are organisms that live in "extreme environments," under high pressure and temperature. Bacteria often form on the rocks near the hydrothermal vents. ... Since they live in “extreme environments” (under high pressure and temperature), they can tell us under which range of conditions life is possible.
Why some organisms or living things can live in extreme conditions on Earth?
Some organisms have developed strategies that allow them to survive harsh conditions. Almost all prokaryotes have a cell wall, a protective structure that allows them to survive in both hypertonic and hypotonic aqueous conditions. ... These are prokaryotes that can tolerate very high doses of ionizing radiation.
Are fungi prokaryotic or eukaryotic?
Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes.
Which is absent in bacteria?
Bacteria are considered as prokaryotic unicellular organisms. Complete step by step answer: -They do not have the membrane-bound organelles like mitochondria, golgi complex. -They only contain ribosomes in the cytoplasm.
What type of DNA is E coli?
The Escherichia coli chromosome or nucleoid is composed of the genomic DNA, RNA, and protein. The nucleoid forms by condensation and functional arrangement of a single chromosomal DNA with the help of chromosomal architectural proteins and RNA molecules as well as DNA supercoiling.
What organisms are used in bioremediation?
In bioremediation, microorganisms with biological activity, including algae, bacteria, fungi, and yeast, can be used in their naturally occurring forms.
Are microbes animals?
ARE MICROBES ANIMALS? Nope. Microbes are single-celled organisms. Animal is a name reserved for multicellular eukaryotes that are heterotrophic, so organisms that are bigger than a single cell and almost all their cells have a nucleus.
What lives in extreme heat?
One type of extremophiles is called thermophiles. These organisms can survive at very high temperatures. In the 1960s, heat resistant bacteria were discovered in hot springs in Yellowstone National Park.
What are examples of extreme environments?
Examples of extreme environments include the geographical poles, very arid deserts, volcanoes, deep ocean trenches, upper atmosphere, outer space, and the environments of every planet in the Solar System except the Earth.
What animal can survive in extreme heat and cold?
Jerboa. Jerboa. This desert-dwelling rodent takes the easy route when it comes to surviving extreme heat: it sleeps in a cool burrow during the day and comes out at night, when it's cooler, to find food.
What are the four organisms?
Organisms are classified by taxonomy into groups such as multicellular animals, plants, and fungi; or unicellular microorganisms such as protists, bacteria, and archaea.
How can bacteria survive in extreme hot or cold?
the bacteria is able to survive in extreme hot or cold conditions because cold shock proteins help the bacteria to survive in temperatures lower than optimum growth temperature and heat shock proteins present in bacteria help to survive in temperatures greater than the optimum temperatures,possibly by condensation of ...
What prokaryotic organisms live in harsh environments?
The Archaea are prokaryotes that inhabit extreme environments, such as inside of volcanoes, while Bacteria are more common organisms, such as E. coli.
