A eukaryote (/juːˈkæri.oʊt/ or /juːˈkæriət/) is an organism whose cells contain complex structures enclosed within membranes. The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus, or nuclear envelope, within which the genetic material is carried. The presence of a nucleus gives eukaryotes their name, which comes from the Greek ευ (eu, "good") and κάρυον (karyon, "nut" or "kernel"). Most eukaryotic cells also contain other membrane-bound organelles such as mitochondria, the Golgi apparatus. In addition, plants and algae contain chloroplasts. Many unicellular organisms are eukaryotes, such as protozoa. All multicellular organisms are eukaryotes, including animals, plants and fungi. aliens
