Introduction The purpose of this experiment was to demonstrate osmosis. Osmosis is the diffusion of water across a selectively permeable membrane (Bell et al 2004). Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration (Brown 1999). Hypertonic is the solution with a higher salt concentration. Hypotonic solution is the solution with the lower salt concentration. My hypothesis is that the potato core will increase in size. When …showed first 75 words of 472 total…

…showed last 75 words of 472 total…that when the potato contained a higher percentage of salt it would increase in size and weight. I would like to test other fruits and vegetables in salt solutions, to test its salt presence. References Bell, Rebekah P., et al. Investigations in Biology 121.
