VACUOLES 

Some animals cells may have  one to a few small  fluid  filled vacuoles.. Plants  cells  in general  possess one or a few  large vacuoles. Vacuoles  of animals  cells arise from golgi  complex  and are hence a part of the cytoplasmic endomembrane  system . Obviously, these are bound  by the same trilaminar units  membrane  these serve for  storage and transport  of dissolved nutritive  secretory  excretoty  substances .  and  for the maintenance  of an intracellular  turgor pressure  some  freshwater  animals  cells  possess one  two  or a few contractile vacuoles  for osmoregulation  such a vacuole is bound  by a simple  and delicate  condensation membrane  different from typical unit membrane.
