If cells are placed in a hypertonic solution containing a solute to which the membrane is impermeable, what could happen?

Question

Quizplus · Accepted Answer

In a hypertonic solution, there is a higher concentration of solute outside the cell than inside. As a result, water will move out of the cell in an attempt to balance the concentration gradient, causing the cell to lose water and shrink. Since the solute is impermeable to the membrane, the cell will not gain any solute and will continue to lose water until it reaches equilibrium or shrinks to the point of being non-functional. Choice A is incorrect because even though the solute cannot pass through the membrane, the solvent (water) can still diffuse out of the cell. Choice B is incorrect because the cells will not return to their original condition unless they are placed back in their original isotonic solution. Choice C is incorrect because the cells will not swell and burst in a hypertonic solution.
