An eukaryote is an organism
formed by one or more complex cells
whit well-developed subcellular compartment, in which the genetic
material (DNA) is organized into a
nucleus. |

They include all the complex life forms
animals, plants, and
fungi, which are mostly
multicellular, as well as
various other groups called protists, many of which are unicellular.
Differently other primitive organisms (such as
bacteria, cyanobacteria and
viruses) lack nuclei and other
complex cell structures, and are called prokaryotes. The eukaryotes
share a common origin, and are often treated formally as a superkingdom,
empire, or domain. |
