also eu·car·y·ote  (yo͞o-kăr′ē-ōt, -ē-ət)
Any of various single-celled or multicellular organisms of the domain Eukaryota, characterized by cells that contain a distinct membrane-bound nucleus and by the occurrence of DNA transcription inside the nucleus and protein synthesis in the cytoplasm, in contrast to prokaryotes.

[eu- + Greek karuōtos, having nuts (from karuon, nut; see kar- in Indo-European roots).]
