Here's why:
* Hypertonic: "Hyper" means "above" or "higher". A hypertonic solution has a higher concentration of solutes (dissolved substances) compared to the inside of a cell.
* Hypotonic: A hypotonic solution has a lower concentration of solutes than the cell.
* Isotonic: An isotonic solution has the same concentration of solutes as the cell.
What happens in a hypertonic solution?
When a cell is placed in a hypertonic solution, water will move out of the cell and into the solution to try and equalize the solute concentration. This can lead to the cell shrinking or becoming dehydrated.
