<P> Eukaryotes ( / juːˈkærioʊt , - ət / ) are organisms whose cells have a nucleus enclosed within membranes , unlike prokaryotes ( Bacteria and Archaea ) . Eukaryotes belong to the domain Eukaryota or Eukarya . Their name comes from the Greek εὖ ( eu , `` well '' or `` true '' ) and κάρυον ( karyon , `` nut '' or `` kernel '' ) . Eukaryotic cells also contain other membrane - bound organelles such as mitochondria and the Golgi apparatus , and in addition , some cells of plants and algae contain chloroplasts . Unlike unicellular archaea and bacteria , eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue . Animals and plants are the most familiar eukaryotes . </P>
