osmoregulation
Contractile vacuole is the clear rounded, pulsating body present in the posterior part of endoplasm of Amoeba. Found only in fresh water and is concerned by osmoregulation, ie, removal of excess of water.
Plasmalemma is a trilaminar and selectively permeable membrane covering the body functions both in excretion and respiration in Amoeba.
Pseudopodia are finger like and blunt extensions of cell body in protozoans. It is a temporary locomotory structure also used for feeding in Amoeba.
