A eukaryote is an organism with a complex cell or cells, in which the genetic material is organized into a membrane-bound nucleus or nuclei. Eukaryotes (also spelled "eucaryotes") comprise animals, plants, and fungi—which are mostly multicellular—as well as various other groups that are collectively classified as protists (many of which are unicellular). In contrast, prokaryotes are organisms, such as bacteria and archaea, that lack nuclei and other complex cell structures. Eukaryotes share a common origin, and are often treated formally as a superkingdom, empire, or domain. In the domain system, eukaryotes have more in common with archaean prokaryotes than bacterial prokaryotes. The name comes from the Greek ευ, meaning good/true, and κάρυον, meaning nut, in reference to the cell nucleus.

- En taxonomía y biología, Eukarya o Eukaryota es el Dominio de organismos celulares con núcleo verdadero. La castellanización adecuada del término es eucariontes. Estos organismos constan de una o más células eucariotas, abarcando desde organismos unicelulares hasta verdaderos pluricelulares en los cuales las diferentes células se especializan para diferentes tareas y que, en general, no pueden sobrevivir de forma aislada. El resto de los seres vivos son unicelulares procariotas y se dividen los dominios Archaea y Bacteria.
- A eukaryote is an organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes are formally the taxon Eukarya or Eukaryota. The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus, or nuclear envelope, within which the genetic material is carried. The presence of a nucleus gives eukaryotes their name, which comes from the Greek ευ (eu, "good") and κάρυον (karyon, "nut" or "kernel"). Most eukaryotic cells also contain other membrane-bound organelles such as mitochondria or the Golgi apparatus. In addition, plants and algae contain chloroplasts. Many unicellular organisms are eukaryotes, such as protozoa. All multicellular organisms are eukaryotes, including animals, plants and fungi.

abstract
| - En taxonomía y biología, Eukarya o Eukaryota es el Dominio de organismos celulares con núcleo verdadero. La castellanización adecuada del término es eucariontes. Estos organismos constan de una o más células eucariotas, abarcando desde organismos unicelulares hasta verdaderos pluricelulares en los cuales las diferentes células se especializan para diferentes tareas y que, en general, no pueden sobrevivir de forma aislada. El resto de los seres vivos son unicelulares procariotas y se dividen los dominios Archaea y Bacteria. Pertenecen al dominio Eukarya animales, plantas, hongos, así como varios grupos denominados colectivamente protistas. Todos ellos presentan semejanzas a nivel molecular (estructura de los lípidos, proteínas y genoma) y comparten un origen común.

- A eukaryote is an organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes are formally the taxon Eukarya or Eukaryota. The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus, or nuclear envelope, within which the genetic material is carried. The presence of a nucleus gives eukaryotes their name, which comes from the Greek ευ (eu, "good") and κάρυον (karyon, "nut" or "kernel"). Most eukaryotic cells also contain other membrane-bound organelles such as mitochondria or the Golgi apparatus. In addition, plants and algae contain chloroplasts. Many unicellular organisms are eukaryotes, such as protozoa. All multicellular organisms are eukaryotes, including animals, plants and fungi. Cell division in eukaryotes is different from that in organisms without a nucleus (Prokaryote). There are two types of division processes. In mitosis, one cell divides to produce two genetically identical cells. In meiosis, which is required in sexual reproduction, one diploid cell (having two instances of each chromosome, one from each parent) undergoes recombination of each pair of parental chromosomes, and then two stages of cell division, resulting in four haploid cells (gametes). Each gamete has just one complement of chromosomes, each a unique mix of the corresponding pair of parental chromosomes. The domain Eukaryota appears to be monophyletic, and so makes up one of the three of domains of life. The two other domains, Bacteria and Archaea, are prokaryotes and have none of the above features. Eukaryotes represent a tiny minority of all living things; even in a human body there are 10 times more microbes than human cells. However, due to their much larger size, their collective worldwide biomass is estimated at about equal to that of prokaryotes. Eukaryotes first developed approximately 1.6–2.1 billion years ago.
