Question

multiple choice question
when a cell is placed in a hypertonic solution, which direction is the net movement of water?

there is no net movement.
into the cell because the cell is smaller than the solution container.
out of the cell because the water is attracted to move toward the higher solute concentration.

Explanation:

To solve this, we recall the concept of osmosis: water moves from an area of lower solute concentration to higher solute concentration. In a hypertonic solution, the solute concentration outside the cell is higher than inside. So water moves out of the cell toward the higher solute concentration. The first option is wrong (there is net movement), the second is wrong (size of cell vs container isn't relevant, it's about solute concentration). The third option matches the osmosis principle.

Answer:

C. Out of the cell because the water is attracted to move toward the higher solute concentration. (Note: Assuming the options are labeled A, B, C with A: There is no net movement, B: Into the cell because the cell is smaller than the solution container, C: Out of the cell because the water is attracted to move toward the higher solute concentration)
