AIM: The aim of the investigation is to see in what solution the weight of the potato tuber not changes after being put in solutions with different concentrations in order to determine the water potential of the potato tissue BACKGROUND THEORY When a plant cell is bathed in a solute of the same water potential, its mass and volume will remain the same, because water enters the cell and leaves at the same rate. OSMOSIS: 1Osmosis is the movement of water molecules from a region of higher water potential to a region of lower...
