What are the differences between hypotonic and hypertonic solution?

ability of an extracellular solution to make water move in or out of a cell by osmosis is known as its tonicity.

A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell.

A hypotonic solution is a particular type of solution that has a lower concentration of solutes on the outside of a cell when compared with the inside of a cell.
