    2562 Words  | 6 Pages

    Determining the Water Potential of Potato Tuber Cells I will carry out an investigation that will enable me to determine the water potential of the tested potato tuber cells. Water Potential is the measurement of the tendency of water molecules to move from one place to another. (Ridge 1991) Water always moves down the water potential gradient, therefore moving from an area of higher water potential to an area of lower water potential. Equilibrium is reached when the water potential

    1850 Words  | 4 Pages

    The Effect of Osmosis on Potato Cells Introduction Osmosis is the movement of water molecules from an area of low concentration (lots of water) to an area of high concentration (little water) through a semi permeable membrane. A semi permeable membrane is a membrane that only lets selected molecules to pass through it. In a plant water is taken into the roots by the process of Osmosis. This is because the cells inside the roots have a higher concentration than the soil outside
