What is the function of contractile vacuole in paramecium?

A. Produces Enzymes
B. Gets rid of excreta
C. Stores and digest food
D. Gets rid of excess water

Correct Answer:

Option D – Gets rid of excess water

Explanation

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
