Question
Biology Question on sense organs
In protozoa like Amoeba and Paramecium, a organ is found for osmoregulation which is
A
Contractile vacuole
B
Mitochondria
C
Nucleus
D
Food vacuole
Answer
Contractile vacuole
Explanation
Solution
The correct option is (A) : Contractile vacuole
The process of controlling the water balance within a protozoan's body is known as osmoregulation. By pushing water out of the cell, contractile vacuoles assist in achieving this. Freshwater protozoans have it, but parasitic and marine protozoans don't. The contractile vacuole is necessary for the control of water balance in amoeba and paramecium.
