A paramecium is a single-celled, freshwater protist that lacks a cell wall but contains a contractile vacuole. The contractile vacuole is surrounded by rings of proteins that can contract when the vacuole is filled with water, expelling the water from the paramecium. What would happen to a paramecium placed into a freshwater aquarium that has been treated with a chemical that disrupts the function of the contractile vacuole?
