Biology coursework Investigation of the effects on potato chips of different sucrose concentrations Introduction Osmosis is the net movement of water molecules from and area of high water potential to an area of low water potential through a partially permeable membrane. In plants, the roots take in water because they have a lower water potential to the low water potential in the root cell, due to the concentration of the cell sap. Due to the extra water that they have taken in, these cells have a higher water potential than the cells next to them, so water is transferred to those cells by osmosis. This is continuous, as when the outer root cells taking water from the ground never get a higher water potential than the ground as most of the water they take in is moved along the roots by osmosis, and then up the stem to the rest of the...
