Investigation of Water Potential of Potato Tuber Cells :: Biology Lab Report

Investigation of Water Potential of Potato genus Tuber CellsIntroductionThis experiment is to find out the water authorization of white potato cells.Water potential is the ability of water to be given and is represented bythe Greek letter (pronounced sy). It tells us which way water willmove and how fast. Water potential is always measured as a damagingnumber this is because the water potential of pure water atatmospherical pressure is zero thusly the stronger a solution is the much ostracise 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(prenominal) 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 building blockfor water potential is kPa because its the measurement of pressureacting on the water molecules.There are two factors that influence water potential* The concentration of solutes inside the cell* The pressure exerted on the cell confine by the stretched call surface membrane or cell wall.Results dodge---------------------------------------------------------------------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.
