उत्तर
Excess of water from the body of the amoeba is collected in the contractile vacuole. Ammonia is soluble in water. Hence, sometimes ammonia is expelled out along with the water from the contractile vacuole.
Function: The contractile vacuole expands when there is water in it and shrinks when the water is released into the surrounding.
