An investigation in to the effects of osmosis on the mass of a potato Introduction In my investigation I studied the effects of different salt solution concentrations, and the effects they had on potato cells. From my preliminary work using three different concentrations, I realised the main objective would be to look at osmosis. Osmosis is a special type of diffusion, as it only involves water molecules, moving from a high concentration to a low concentration through a semi-permeable membrane. When the water moves from a high concentration to a low concentration the water enters the cell, which increases the pressure causing it to become turgid. When this occurs to the potato it will expand. The opposite of this is when water leaves the cell this means there is no pressure within and the potato shrinks when this process occurs the potato is said to be flaccid. Therefore I can conclude that...
