Answer 2

The absence will lead to death of amoeba.

• Contractile vacuole is a membrane bound cell organelle that has an very important role in osmoregulation.
• It helps regulate the water balance of cell by removing excess water out of the cell through contraction.
• In absence of contractile vacuole, excess water accumulated in amoeba through osmosis will not be pumped out, thus causing it to burst.
