eukaryote

n. organism made up of cells that have cell organelles and nuclei with chromosomes (characteristic of all cells except for bacteria and other very primitive life forms)

Animals, plants, fungi, and protists are eukaryotes , 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. In the nucleus, the genetic material, DNA, is arranged in chromosomes. Many eukaryotic cells also contain membrane-bound organelles such as mitochondria, chloroplasts and Golgi bodies. Eukaryotes often have unique flagella made of microtubules in a 9+2 arrangement.
