eukaryote

World Encyclopedia | 2005 | Copyright

eukaryote Organism whose cells have a membrane-bound nucleus, with DNA contained in chromosomes. Making up one of the three domains, eukaryotes include all animals, plants, fungus, and Protoctista. They have a complex cytoplasm with an endoplasmic reticulum, and most of them possess mitochondria. Most plants and algae also possess chloroplasts. Other structures specific to eukaryotic cells include microtubules, Golgi bodies, and membrane-bound flagella. See also Golgi body; kingdom; mitochondrion; prokaryote
