An Experiment to Find discover the Effect of Osmosis on Potato Cells Plan ==== Apparatus A bore bit 25 test tubes 5 test tube racks 2 potatoes A ruler A sharp knife Variables Four different wampum solutions at 10%,20%,30%and40% and distilled water Hypothesis I hypothesis that the high the sugar the less the potato size will increase. I forecast this because I think it will be harder for the liquid to get in because it is denser. Using the borer make cuts into the potato and pull out the pieces of potato. whirlybird the pieces so they are 20mm long repeat process 25 times. This try must be statistic aloney viable i.e. the potato pieces must be identical. If you come to a bad piece of potato discard it. beat all the pieces into individual test tubes. Using one of the solutions fill up 5 test tubes to exactly the same height. Repeat process for all the solutions. Put test tubes into racks and leave for 24 hours. This should be d one as quickly as possible to ensure each piece of potato is immersed for exactly the same period of time. Research IMAGEFig 1 Osmosis is the conveyance of a liquid solvent through a semi permeable tissue layer that does not allow dissolved solids (solutes) to pass. Osmosis refers only to transfer of solvent transfer of solute is called dialysis . In either case the direction of transfer is from the area of high concentration of the hooey transferred to the area of note concentration. This spontaneous migration of a material from a region of higher concentration to a region of lower concentration is called diffusion. Osmosis will occur if a vessel is separated into twain compartments by a semi permeable membrane, both compartments are change to the same level with a solvent, and solute is added to one side. The level of the liquid on the side containing the solute will
