Biology Coursework Effect of Different Concentrations of Sucrose on Potato Tissues AIM Aim of this experiment is to investigate and understand how diffusion process allows movement of molecules from one concentration of solution to a different concentration of solution. I will conduct an experiment by immersing a sliced potato in different concentration of sucrose solution and measure mass of the potato at intervals to see if diffusion has taken place. Potato is chosen because its cells contain starch (carbohydrates) within it. (This proof was obtained using iodine solution. The solution turned blue/ black in colour because there was starch present). Since sugar molecules are large the theory says it will take longer for the molecules to diffuse. This will allow us to see the diffusion take place both ways, into the cell and out of the cell. The results from this experiment will allow me to understand how chemical exchange takes place within living...
