Quizplus · Accepted Answer

The contractile vacuole helps single-celled organisms maintain homeostasis in a hypotonic environment by pumping out excess water that enters the cell through osmosis. Without the contractile vacuole, the cell could burst due to the influx of water. Therefore, option A is the correct choice.
