Definitions:

Hypertonic

Describes a solution that has a higher concentration of solutes compared to another solution, causing cells in contact with it to lose water through osmosis.

Hypotonic

describes a solution that has a lower concentration of solutes compared to another solution, leading to water moving into the cell.

Isotonic

A solution that has the same solute concentration as another solution, preventing the movement of water across a semipermeable membrane.

Osmosis

The spontaneous movement of solvent molecules through a semi-permeable membrane from a region of lower solute concentration to one of higher solute concentration.
