Investigation of Water Potential of Potato Tuber CellsIntroductionThis experiment is to rise out the weewee potential of potato cells.Water potential is the ability of irrigate to move and is represented bythe Greek letter (pronounced sy). It tells us which government agency piss willmove and how fast. Water potential is always measured as a negativenumber this is because the water potential of pure water atatmospheric pressure is zero therefore the stronger a solution is the more(prenominal) negative the number. This is because a solution has solutespresent and solute molecules slow the movement of the water molecules,therefore always making the water potential of a solution less thanzero.The stronger the concentration the slower the movement of watermolecules present due to more bonds between the solutes and the watermolecules, therefore the more negative the water potential. The unitfor water potential is kPa because its the measurement of pressureacting on the water molecul es.There are two factors that influence water potential* The concentration of solutes inside the cell* The pressure exerted on the cell contents by the stretched vociferate surface membrane or cell wall.Results Table---------------------------------------------------------------------Concentration Mass before Mass after Change in 0 (distilled (m) (g) (g) Mass(g) water) 1.32 1.47 0.15 0.2 1.35 1.36 0.01 0.4 1.24 1.16 -0.08 0.6 1.38 1.05 -0.33 0.8 1.57 1.
