The Biological Effects of Tonicity

The video explains tonicity, which is the ability of external solutions to change the water content inside cells. It covers three types of solutions: hypotonic, isotonic, and hypertonic. Hypotonic solutions cause cells to swell, isotonic solutions maintain equilibrium, and hypertonic solutions lead to cell shrinkage. The effects on both red blood cells and plant cells are discussed, highlighting the role of osmosis in these processes.
