Eukaryotes

The eukaryotes () are the domain of Eukaryota or Eukarya, organisms whose cells have a membrane-bound nucleus. All animals, plants, fungi, seaweeds, and many unicellular organisms are eukaryotes. They constitute a major group of life forms alongside the two groups of prokaryotes: the Bacteria and the Archaea. Eukaryotes represent a small minority of the number of organisms, but given their generally much larger size, their collective global biomass is much larger than that of prokaryotes.

Disparia () is a supergroup of eukaryotic microbes. It represents one of the five primary clades within Diaphoretickes, although its exact position in this group is unclear. While this clade of protists is not particularly species-rich compared to other supergroups, the species within it are particularly diverse. The clade Promethea has a definition similar to that of Disparia, and the two have an identical taxonomic composition.
