An investigation into osmosis in plant cells Aim: To see what happens to the length of a piece of potato during osmosis into different concentrations of sucrose solution. Prediction: Osmosis is a special case of diffusion. There is a low concentration of solute molecules and a high concentration of water molecules . Inside the cell, there is a high concentration of solute molecules and a low concentration of water molecules. The solute molecules can't diffuse out because the plasma membrane won't let them through. The water molecules however can diffuse in - this is osmosis. Osmosis can be defined as the passage of water molecules through a partially permeable membrane, from a region where they are in higher concentration to a region where they are in a lower concentration. Using the information that I have just written. I predict that the higher the concentration (meaning the amount of sucrose in...
