Final answer:
In isotonic solutions, there is no net movement of water into or out of the cell. In hypertonic solutions, water leaves the cell, causing it to shrink. In hypotonic solutions, water enters the cell, causing it to swell and potentially burst.
Step-by-step explanation:
In an isotonic solution, the concentration of solutes is the same inside and outside the cell. This means that water flows in and out of the cell at the same rate, resulting in no change in the size of the cell.
In a hypertonic solution, the concentration of solutes outside the cell is higher than inside the cell. Water will move out of the cell, causing it to shrink and shrivel.
In a hypotonic solution, the concentration of solutes outside the cell is lower than inside the cell. Water will move into the cell, causing it to swell and potentially burst.
