Saccharomyces cerevisiae was the first eukaryotic organism to have its complete genome sequence determined.. This list of "sequenced" eukaryotic genomes contains all the eukaryotes known to have publicly available complete nuclear and organelle genome sequences that have been sequenced, assembled, annotated and published; draft genomes are not included, nor are organelle-only sequences.
Stentor coeruleus, used in molecular biology (its genome has been sequenced), [5] and is studied as a model of single-cell regeneration.; Dictyostelium discoideum, used in molecular biology and genetics (its genome has been sequenced), and is studied as an example of cell communication, differentiation, and programmed cell death.
The multicellular eukaryotes include the animals, plants, and fungi, but again, these groups too contain many unicellular species. [10] Eukaryotic cells are typically much larger than those of prokaryotes —the bacteria and the archaea —having a volume of around 10,000 times greater.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms. This number, along with the visual appearance of the chromosome, is known as the karyotype , [ 1 ] [ 2 ] [ 3 ] and can be found by looking at the chromosomes through a microscope .
List of eukaryotic species that belong to picoplankton, meaning one of their cell dimensions is smaller than 3 μm. Autotrophic species. Chlorophyta. ...
Eukaryotes by taxonomic classification : The unranked clade Bikonts contains plants, algae , the unranked group Excavata of symbiotic or parasitic organisms, the unranked clade Sar or Harosa (SAR supergroup) and Hacrobia , a proposed monophyletic group of unicellular eukaryotes not included in the SAR supergroup.
The three-domain system adds a level of classification (the domains) "above" the kingdoms present in the previously used five- or six-kingdom systems.This classification system recognizes the fundamental divide between the two prokaryotic groups, insofar as Archaea appear to be more closely related to eukaryotes than they are to other prokaryotes – bacteria-like organisms with no cell nucleus.
SAR or Harosa is a highly diverse clade of eukaryotes, often considered a supergroup, [2] that includes stramenopiles (heterokonts), alveolates, and rhizarians. [3] [4] [5] It is a node-based taxon, including all descendants of the three groups' last common ancestor, [6] and comprises most of the now-rejected Chromalveolata. [2]
