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
