  • Why must an aquatic organism, such as an amoeba, constantly use a contractile vacuole to transport water out of the cell?
Oct 22nd, 2017

The vacuole regulates internal mineral salt concentrations when living in hypotonic (low solute) environments like freshwater. The amoeba experiences osmosis; there is a net diffusion of water across the cell membrane, drawn by the high salt concentration the amoeba maintains.
