and bacteria grow and reproduce; they are operationally plants.
are specialised to live in extremes of temperature, pH, salinity and pressure other forms of prokaryotes are capable of occupying all other possible ranges.

, Eubacteria, and Eukaryotes," Microbiology and Molecular Biology Reviews 62 (1998): 1435-91.
Computer analyses of complete genomes suggest that some archaebacteria
employ both eukaryotic and eubacterial mechanisms in translation initiation.
AND EUBACTERIA CONCENTRATIONS IN AQUATIC AREAS OF THREE DIVERSE SALINE ENVIRONMENTS.
Woese therefore proposed that living organisms be classified under three domains: Eubacteria, Archaebacteria
, and Eukaryota.
The sequences encompass at least seven groups of methane-producing microbes of a type called archaebacteria
Messenger RNA molecules (mRNAs) lacking 5' untranslated leader sequences have been observed in eubacteria, archaebacteria
, and eukaryotic mitochondria (see 1 and references cited therein).
Although, as previously noted, "Non-Neutral Evolution" has a definite Drosophila bias, it is not as monochromatic as perhaps this review has made it sound: oysters (Beckenbach) and halophilic archaebacteria
(Dennis) make appearances, and even vertebrates get a look-in in the final, largely theoretical, chapter by Takahata.
Identification was made using 16S rDNA, a powerful tool for deducing evolutionary relationships and phylogenetic among eukaryotic organisms, bacteria and archaebacteria
(Olmezoglu et al.
In order to simplify the task, we decided to use the classification categories provided in the textbook (Miller & Levine, 2001), excluding archaebacteria
Unlike bacteria and archaebacteria
, the choanoflagellate cell has a clearly defined nucleus.
represents a new species within the sulfate-reducing archaebacteria
In today's world, prokaryotes are exemplified by organisms known as bacteria and archaebacteria
, which inhabit every conceivable biological niche on the planet.
Phylogenies based on biochemical data indicate that eukaryotic mitochondria are a sister-group of the [alpha]-purple eubacteria, while eukaryotic cells are a sister-taxon to the archaebacteria
