Explain how Amoeba sp. can survive in hypotonic freshwater against the citoplasm of such organisms

To regulate osmotic pressure, most freshwater amoebae have a contractile vacuole (CV) that expels excess water from the cell. This organelle is necessary because the surrounding water is hypotonic with respect to the contents of the cell. Water is transferred across the amoeba's cell membrane by osmosis
