Essay On Archaea

This paper will refer to the domain of Archaea. The archaea are single-celled prokaryotes that were classified in the bacteria domain naming them the Archaeabacteria. Until just recently the scientific community decided that these special creatures belonged in their very own domain. The archaea resembled the eukaryotes more than the bacteria even though they were still a prokaryotic organism. So these micro-organisms had to be moved into its own domain.
These organisms are what many biologists call the “Life Extremists”. They are found in places that have horrible environmental conditions. Places like a hot springs in Yellowstone National Park or even found in the stomach of humans and cows to help with digestion. Some scientists believe these organisms may be the oldest living inhabitants on planet Earth. Some micro-biologists also believe we will see some archaean organisms on a moon in our very ownsolar system.

Introduction: There are three domains Bacteria, Archaea, and Eukarya. This is …show more content…
These organisms are similar in structure to bacteria, being single-celled and no nucleus, hence the name Archaeabacteria. Just recently the scientific community gave these highly adaptable organisms their very own domain. With some extensive research scientists believe Archaea has nothing in common with Bacteria. One of the differences is the archaea have no peptidoglycan in their cell walls and that archaea is closely related to the eukaryotes by from having chloroplasts or mitochondria to produce energy for cells. The Phylogeny of the Archaea has these phyla: Thaumarchaeota, Crenarchaeota, Korarchaeota, Nanoarchaeota, and Euryarchaeota. These Archaea organisms could very well be the oldest living species on this planet and within the next five years, some astrobiologists may find what we consider a life form on another moon in our solar system that resembles these Archaea
