eukaryote
[ yōō-kăr′ē-ōt ]
An organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins (histones) into chromosomes. The cells of eukaryotes also contain an endoplasmic reticulum and numerous specialized organelles not present in prokaryotes, especially mitochondria, Golgi bodies, and lysosomes.

All organisms except for bacteria and archaea are eukaryotes. Compare prokaryote.
