Definitions:

Osmosis

The movement of water molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.

Salt Molecules

consist of positive ions (cations) and negative ions (anions) held together by ionic bonds, commonly exemplified by sodium chloride (NaCl).

Hypotonic

Describes a solution with a lower concentration of solutes compared to another solution, leading to cell swelling if the cell is placed in such a solution.

Isotonic

A solution that has the same salt concentration as the normal cells and blood of an organism, resulting in no net movement of water across the cell membrane.
