The consistent use of the taxonomic system of binomial nomenclature (genus and species) was first popularized by Linnaeus nearly threehundred years ago to classify mainly plants and animals. Keeping the phylogenetic categorization of archaebacteria under the domain Archaea aside, the archaebacterial representatives can be grouped as under on the basis of their strange metabolic and ecological characteristics: methanogens, extreme halophiles, extreme thermophiles, thermoacidophiles and thermophiles.
Halophiles are typically categorized as slight, moderate, or extreme based on the amount of salt they can tolerate in their environment. Halophiles Examples While there are not a lot of known species of halophiles, the ones that have been discovered are quite diverse.
Classification. Halophiles are categorized as slight, moderate, or extreme, by the extent of their halotolerance. Slight halophiles prefer 0. 3 to 0. 8 M (1. 7 to 4. 8seawater is 0. 6 M or 3. 5), moderate halophiles 0. 8 to 3. 4 M (4. 7 to 20), and extreme halophiles 3. 4 to 5. 1 M (20 to 30) salt content. Extremophiles: Life in an Extreme Environment Essay Sample Extremophiles are organisms, mostly unicellular, which are able to tolerate and thrive in or utilize resources in extreme conditions.
Biotic or living forms on earth fall under three domains: Archaea, Bacteria and Eukarya. of archaebacteria, the extreme halophiles, thrives in areas with high salinity, which one might have a priori believed to rule out any life form: lakes or seas with salinity as high as 300 grams of salt per liter. Use the multiplechoice questions of this interactive quiz to test your knowledge of halophiles and their classification. For additional support, Three Domain System of Classification Essay Sample.
The Earth is 4. 6 billion years old and microbial life is thought to have first appeared between 3. 8 and 3. 9 billion years ago; in fact, 80 of Earths history was exclusively microbial life. Methanogens, Halophiles, and Thermoacidophiles are found in the Archaea Extreme halophiles classification essay. They once believed to be a form of bacteria, but are no longer classified as bacteria. They live in extreme environments and are stll sometimes classified under archaebacteria.
They are thought to be the oldest form of life found on earth. Apr 11, 2010 This Site Might Help You. RE: What is the COMPLETE classification of Halophiles? PLEASE HELP ASAP! ? I desperately need the COMPLETE classification (Kingdom, Phylum, Class, Order, Family, Genus, Species) for the Archaebacteria Halophiles.
