Salt Potato

scenario Plants in the soil have their roots in a dilute solution of mineral ions. When they are suddenly flooded with seawater, concentration of which is 0.3 molar Sodium Chloride, they are observed to wilt and become flaccid. Aim The aim of this experiment is to investigate the movement of water into and out of plant cells by osmosis. The cells chosen for study will be taken from potato tubers as they provide a ready supply …

…top pan balance, which was to one decimal place, and the calibration of the ruler. It was also unlikely that room temperature and pressure remained consistent throughout the experiment conduction, and changes in temperature may have altered the rate of diffusion. The potato cores should have had any excess water on their outer surfaces removed by blotting with blotting paper before being re-measured, as this is likely to have altered the masses of the cores.
