Eucarya

one of the three primary groupings (DOMAINS) of ORGANISMS in modern classifications based on genetic structures and sequences. See CLASSIFICATION. It contains a number of KINGDOMS or groupings of kingdom rank including ANIMALS, PLANTS, ENTAMOEBAE, SLIME MOULDS, FUNGI, CILIATES, FLAGELLATES, TRICHOMONADS, MICROSPORIDIA and DIPLOMONADS. These are all EUKARYOTES, having cells with well-defined NUCLEI.
