This video is a review of hypotonic, hypertonic and isotonic solutions, how they lead to plasmolysis, cytolysis and dynamic equilibrium. In addition to tonicity, the video also covers concentration gradients, solutes and solvents, and whether you should drink salt water in a survival situation.
Remember that "hypertonic", "hypotonic" and "isotonic" are all relative terms (like "bigger" or "shorter"). A hypertonic solution is saltyER than something else (in this case, the cell that's placed in it). It might not be very salty at all, it just has to be MORE salty relative to another solution or object.
These concepts are extremely useful in medicine. IV fluids, for instance need to be the correct tonicity in order to achieve the desired effects.
