A hypotonic solution has a lower concentration of solutes compared to another solution, usually a cell. This means it has a higher concentration of water than the cell.

Here's why:

* Solute: A substance dissolved in a solvent (like water).

* Solvent: The substance that dissolves the solute.

* Solution: The mixture of solute and solvent.

In a hypotonic solution, there are fewer solutes compared to the cell. Since water naturally moves from an area of high concentration to low concentration, water will flow into the cell to try to balance the solute concentrations. This can cause the cell to swell or even burst.
