Water potential of potato tuber cells - the weighing method The Investigation of Osmosis The investigation was to find the differences in water molecules moving from an area of high concentration to an area of low concentration using potato tubes and varying the concentration of the solutions. The way in which water molecules do this is called osmosis. Osmosis is the movement of water through a semi-permeable cellulose wall and cell membrane along a water potential gradient. From previous research I predict that as the concentration of the solution outside the potato tubes is increased there will be a increase in the number of water molecules moving from the solution into the potato tubes, and also then as the concentration of the solution decreases there will be an increase in the number of water molecules moving from the potato tubes. Using this investigation we will also be able to work out...
