Eukaryotes    

By  a  plasma  membrane, a  eukaryotic  cell  is  surrounded which has  a  membrane- bound nucleus  and contains  a number  of other distinct  sub cellular  organelles.  These  organelles  are  membrane-bounded  structures,   each  having  a unique  role  and  each  containing  a particular  complement  of proteins  and  other molecules. Animal and plant cells are having the same basic structure, though some organelles and structures are found in one and not the other (For example: vacuoles, chloroplasts and cell wall in plant cells, lysosomes in animal cells).
