I am doing a report on how to tell the difference between hypotonic, isotonic, and hypertonic solutions.  We used four different situations: Distilled water, pond water, 0.9% Saline, and 10% Saline. We used all four of these conditions to test two specimens: a Elodea plant leaf, and a few drops of rat blood. How do I tell which ones are which???? Which one is hypertonic, hypotonic, isotonic??? HELP???? Thanks

The names corresponds to which osmotic effect they excert on the cells. Maybe you can look in a microscope to see which solution makes the cells swell (hypotonic), lyse (hypertonic) or no change at all (isotonic)

Good luck
