What are the difference between hypertonic, isotonic, and hypotonic?

hyper- over

hypo- below

iso- equal

Ex: a cell with a semipermeable membrane is put in the following solutions

Hypertonic solution;

this means that the solute is more concentrated on the outside of a cell

water would move out of the cell to dilute to  the concentration

the cell would shrivel

Hypotonic solution:  

this would mean solute is more concentrated on the inside of a cell

water would move into the cell

the cell could burst or lyse

Isotonic solution:

the solute is in equal concentrations inside and outside of the cell

it is in equilibrium

water still moves in and out of the cell though

answer; i believe the answer is (polygenic inheritance;
