Aim- To find if the concentration of the external solution affects osmosis in plant tissue. I will be investigating how molrality of a salt solution affects the mass and length of potato chips during osmosis. Background information. Osmosis is a special kind of diffusion involving the movement of water molecules. Water molecules are small and can pass easily through a particularly permeable membrane that will prevent the movement of larger molecules. This special kind of diffusion only occurs when a partially permable membrane seperates two solutions. So osmosis is the movement of water through a partially permable membrane from a region of high water concentration to a region of lower water concentration. The water is said to move down a concentration gradient. Preliminary work Aim- To find if the concentration of the external solution affects osmosis in plant tissue. I will be investigating how morality of a salt solution affects the mass...
