  EUKARYOTES DEFINITION ; ➤ EUKARYOTES HAVE WELL DEFINED NUCLEUS, IN WHICH  NUCLEAR     MATERIAL (CHROMOSOME OR DNA) IS ENCLOSED  IN DOUBLE NUCLEAR     MEMBRANE.  ORGANELLES; ➤ EUKARYOTIC CELLS HAVE MEMBRANE BOUND ORGANELLES LIKE      MITOCHONDRIA, GOLGI APPARATUS, ENDOPLASMIC RETICULUM ETC. RIBOSOMES; ➤ THE RIBOSOMES OF EUKARYOTIC CELLS ARE LARGER IN SIZE AS    COMPARED TO  THE RIBOSOMES OF PROKARYOTIC CELLS. SIZE OF EUKARYOTIC CELLS; ➤ EUKARYOTIC CELLS ON AVERAGE, TEN TIMES LARGER  THAN       PROKARYOTIC CELLS. CELL WALL; ➤ THE CELL WALL OF EUKARYOTIC CELL IS MADE OF CELLULOSE IN     (PLANTS) OR CHITIN IN (FUNGI).  FOR EXAMPLE; ➤ EUKARYOTES INCLUDE ALL  OTHER UNICELLULAR  OR MULTICELLULAR    ORGANISMS LIKE ANIMALS, PLANTS, FUNGI,PROTISTA.   STRUCTURE OF ANIMAL CELL; click here to see prokaryotes
