  • The Effect of Salt Concentration on Osmosis in Potato Cells

    The Effect of Salt Concentration on Osmosis in Potato Cells We should first explain what Osmosis is. It’s a passage of water from a region of high water concentration through membrane to a region of low water. Semi membrane is a very thin layer of material, which allows some things to pass through them...
