archaea : microorganisms of a domain including especially methane-producing forms, some red halophilic forms, and others of harsh hot acidic environments (as a hot spring) (archaea, 2015) [1]blank.gifWebster | OneLook | Visuwords
Archaea are a group of single-celled microorganisms. A single individual or species from this domain is called an archaeon (sometimes spelled "archeon"). They have no cell nucleus or any other membrane-bound organelles within their cells. In the past they had been classed with bacteria as prokaryotes (or Kingdom Monera) and named archaebacteria, but this classification is regarded as outdated. In fact, the Archaea have an independent evolutionary history and show many differences in their biochemistry from other forms of life, and so they are now classified as a separate domain in the three-domain system. In this system, the phylogenetically distinct branches of evolutionary descent are the Archaea, Bacteria and Eukaryota. (Archaea, 2015) [2]blank.gif Wikipedia
