TO FIND THE WATER POTENTIAL OF PLANT TISSUE CELLS. AIM: To find the water potential of plant tissue cells by using different sucrose concentrations. What is water potential? Water potential is the ability of water to enter or leave a cell that is measured in Kilopascals(Kpa).Water can enter or leave a cell by the process called 'Osmosis', this is the movement of water from a region of high water potential to that of low water potential through a partially permeable membrane e.g. plasma membrane. Pure water is said to have a water potential of zero and it follows that the addition of solutes to pure water lowers its water potential, therefore the more solute added to pure water, the more negative its water potential. STRUCTURE OF A PLANT CELL. PREDICTION. When a cell is put in a highly concentrated sucrose solution, the water will move by osmosis from the cell to the solution because the...
