Question

Major function of contractile vacuole of Amoeba and others is

• A. Circulation
• B. Excretion
• C. Osmoregulation
• D. All of the above

Answer 1

Answer: (C)

Amoeba is a unicellular organism. A contractile vacuole works just the same as the name suggests, in that it expands and contracts. The function of the contractile vacuole is to pump water out of the cell through a process called osmoregulation, the regulation of osmotic pressure. Hence the major function of contractile vacuole of amoeba and others is osmoregulation,

So, the correct answer is 'Osmoregulation'.
