Eukaryotes (IPA: [juːˈkæɹɪɒt]) are organisms whose cells are
organized into complex structures by internal membranes and a
cytoskeleton. The most characteristic membrane bound structure is the
nucleus. This feature gives them their name, (also spelled "eucaryote,")
which comes from the Greek ευ, meaning good/true, and κάρυον, meaning
nut, referring to the nucleus. Animals, plants, fungi, and protists are eukaryotes.
