An Experiment to Determine the Water Potential (?) of a Plant Tissue, using Discs of Beetroot Introduction Water potential (?) is the measurement of the ability of water molecules to move within a cell. A high water potential (?) is achieved when there is a high water concentration within a cell. The water molecules create an outward force on the cell membrane and wall, which makes the pressure within the cell high. Plant cells with a high water potential (?) become turgid, because of the cell wall's ability to stretch slightly to reduce the pressure within the cell. Animal cells do not have cell walls and therefore lack in the ability to reduce this pressure. If the water potential (?) in an animal cell becomes too great, the cell membrane will break and the cell will have burst under the pressure. The concentration of water in a cell is controlled by several...
