Investigating Osmosis in a Potato Cylinder Aim: To investigate osmosis in sugar solution using potato cells. Prediction: To make my prediction, I am basing it on my background information and on my preliminary tests. I predict, the larger concentration of sucrose, will decrease the lengths of the potato cylinders. Osmosis ( a diffusion of water) will occur across a semi permeable membrane when there is a difference between the water concentrations on the two sides of the membrane. Knowing this, water will flow through them making cells turgid or plasmolysed if water flows out of them and all this will change the volume. I also predict that the isotonic solution will be 0.3 molarity solution. Background Information: From the Oxford Biology book, and the encyclopaedia. This is the information I had obtained and also using the information from my preliminary test. If the concentration is great then the potato cylinder will contract by...
