Question

When a cell is placed in an isotonic solution, water will:
A) move into and out of the cell at an equal rate and not affect the cell.
B) move into the cell and cause the cell to burst.
C) move out of the cell and cause the cell to shrink.

Accepted Answer

In an isotonic solution, the concentration of solutes is equal inside and outside the cell, so water moves in and out at equal rates, maintaining cell size.
