Answer:

Hypotonic solution

Explanation:

hypertonic solution is the one you get when the solute concentration of the water is higher than that of the cells.

isotonic solution is the one you get when the solute concentration of the cell and the water are the same.

hypotonic is the one that you get when the solute  concentration of the cell is higher than that of the waters.

Solute concentration being low reminds me of water. Hypo kind of sounds like hippo and hippos love water. You can use this to memorize the difference between hypertonic and hypotonic solutions.

sorry if the grammer is bad i tried my best.
