An investigation to demonstrate osmosis using a potato Aim I am going to investigate osmosis when potato is placed in different concentrations of sucrose. I am aiming to witness osmosis in 6 different concentrations of sucrose. I will use 6 varying concentrations so that I have a wider spread to compare the results, and check that I don't have any anomalies. Prediction Osmosis is the process of diffusion of water molecules from a weaker solution into a stronger solution, through a semi permeable membrane. The tiny pores in the membrane of the potatoes will allow the water molecules to go in and out of the potato cell, depending on the concentration gradient between the potato and the sucrose solution. If the water concentration is lower in the potato than in the sucrose solution, then water will pass from the sucrose solution into the potato, and it will gain weight. If there is a higher...
