The contractile vacuole helps the paramecium to survive in freshwater environments by removing the excess water and preventing cell swelling.

Vacuoles are membrane-bound organelles that are responsible for osmotic regulation or the discharge of excess water from cells.

Paramecia is a group of unicellular organisms in which the excess water is removed by the pumping action of contractile vacuoles.

Thus, in Paramecia, contractile vacuoles are considered to be excretory structures.

In conclusion, the contractile vacuole helps the paramecium to survive in freshwater environments by removing the excess water and preventing cell swelling.
