Osmosis in Potato Tubers Andrew Dickson Background When a plant cell is bathed in a solution of the same concentration (isotonic) as its intracellular environment‚ its mass and volume remain the same. This is because water enters and leaves the cells at the same rate. There is no net loss or gain of water by osmosis. Samples of cells can be placed in a range of solutions of different concentration. The cells will gain water by osmosis when placed in solutions which are more dilute (hypotonic)

Since potato cells were used for this type of experiment‚ in an Isotonic solution the solute and water concentration are the same as inside the cell in which the isotonic solution contains 0.9% NaCl. In other words‚ water moves in and out in the same amount without causing any changes. In a hypertonic environment‚ the solute concentration is greater and water concentration is less outside the potato cell in which the hypertonic solution contains 10.0% NaCl. This solution will cause the potato cells
