Aim. My aim is to investigate osmosis in plant cells. I will do this by carrying out an experiment to find out the percentage increase or decrease in mass (grams) of potato tube, placed in varying concentration of glucose. Background Information - The theory of Osmosis. Osmosis is a special case of diffusion that involves water. It is the movement of water molecules across a partially permeable membrane from a region of high water concentration to a region of low water concentration until equilibrium is reached. This means that only water molecules can pass through the partially permeable membrane due to it being small enough to fit through. Bigger molecules such as glucose would not be able to get through. Also Osmosis makes plant cells swell up or turn turgid when the cell is placed in a solution containing a higher concentration of water, or shrivel up when placed in a low...
