Here's a breakdown:

* Hypotonic solution: A solution with a lower solute concentration than the cell's interior.

* Water movement: Water will move from the area of higher water concentration (outside the cell) to the area of lower water concentration (inside the cell) to try and equalize the solute concentrations.

* Result: The cell will swell or even burst (lyse) as water rushes in.
