The '''eukaryotes''' ({{IPAc-en|j|uː|ˈ|k|ær|i|oʊ|t|s|,_|-|ə|t|s}} {{respell|yoo|KARR|ee|ohts|,_|-|əts}}) constitute the [[Domain (biology)|domain]] of '''Eukarya<!--yes, this isn't a typo-->Eukaryota''', [[organism]]s whose [[Cell (biology)|cells]] have a membrane-bound [[cell nucleus|nucleus]]. All [[animal]]s, [[plant]]s, [[Fungus|fungi]], and many [[unicellular organism]]s are eukaryotes. They constitute a major group of [[Outline of life forms|life forms]] alongside the two groups of [[prokaryote]]s: <!--namely -->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.
 
The eukaryotes seemingly emerged in the Archaea, within the [[Asgard (archaea)|Asgard archaea]]. This implies that there are only [[Two-domain system|two domains of life]], Bacteria and Archaea, with eukaryotes incorporated among the Archaea. Eukaryotes first emerged during the [[Paleoproterozoic]], likely as [[Flagellated cell|flagellated]] cells. The leading [[evolutionary]] theory is they were created by [[symbiogenesis]] between an anaerobic Asgard archaean and an aerobic [[proteobacterium]], which formed the [[Mitochondrion|mitochondria]]. A second episode of symbiogenesis with a [[Cyanobacteria|cyanobacterium]] created the plants, with [[chloroplast]]s.
