If cells are placed in a hypotonic solution containing a solute to which the membrane is impermeable, what could happen?
A) The cells will show no change due to diffusion of both solute and solvent.
B) The cells will lose water and shrink.
C) The cells will shrink at first, but will later reach equilibrium with the surrounding solution and return to their original condition.
D) The cells will swell and ultimately burst.

In a hypotonic solution, the concentration of solute is lower outside the cell than inside. Since the cell membrane is impermeable to the solute, water will move from the hypotonic solution into the cell by osmosis. This will cause the cell to swell, and if the cell cannot regulate its volume, it will eventually burst, a process called cytolysis.
