Solution:
Contractile vacuole is a membrane-surrounded cavity in a cell that periodically expands, filling with water, and then suddenly contracts, expelling its content to the cell’s exterior. It is thus an organ of osmoregulation and excretion. Contractile vacuoles are common in fresh water sponges, Amoeba, and Paramecium.
