Imagine an artificial cell made with a selectively permeable membrane that allows water to pass through but does not allow sugar to pass. If the artificial cell contains a 1% sugar solution and then you place the cell in a 2% sugar solution, what happens?
A) Sugar diffuses in and water diffuses out until equilibrium is reached.
B) Water enters the cell because the solution is hypotonic to the cell.
C) There is no movement of water.
D) Water leaves the cell because the solution is hypertonic to the cell.

Water leaves the cell because the external solution is hypertonic (2% sugar) compared to the internal solution (1% sugar), leading to water moving out to try to balance the concentration gradient.
