What is the function of the contractile vacuole in paramecium?
Produces enzymes
Gets rid of excreta
Stores and digests food
Gets rid of excess water
Correct answer is D
Osmoregulation: Paramecium and amoeba live in fresh water. Their cytoplasm contains a greater concentration of solutes than their surroundings and so they absorb water by osmosis. The excess water is collected into a contractile vacuole which swells and finally expels water through an opening in the cell membrane.
Excretion of water in Paramecium is carried out by the Contractile vacuoles.
