Which saltwater concentration will have the most damaging effects on potato cells introduction osmosis is the diffusion of water across a selectively permeable membrane. Osmosis can be demonstrated when potato slices are added to a high salt solution the water from inside the potato moves out to the solution, causing the potato to shrink and to lose its 'turgor pressure' the more concentrated the salt solution, the bigger the difference in size and weight of the potato slice in unusual environments, osmosis. 2 experiment to demonstrate osmosis in living tissues materials 3 irish potato halves (raw) 3 petridishes 2 tea spoonfuls of salt (osmosisosmosis is defined as the movement of water molecules.
