What will be the direction of flow of water when a plant cell is placed in a hypotonic solution?

1. No flow of water in any direction.
2. Water will flow in both directions.
3. Water will flow out of the cell.
4. Water will flow into the cell.

Correct answer: Water will flow into the cell.

Solution

A hypotonic solution has a lower solute concentration than the plant cell, so water enters the cell by osmosis. This makes the cell become turgid as water moves inward.
