Practical assesment about biology: To determine the water potential of potato tuber cells

OSMOSIS Aim To determine the water potential of potato tuber cells. Background knowledge Osmosis is defined as the movement of water molecules from a region of higher water potential to a region of lower water potential through a partially permeable membrane. Osmosis is considered in terms of water potential and solute potential. Water potential is a measure of the kinetic energy of water molecules. Here, water molecules are constantly moving in a random fashion. Some …showed first 75 words of 3969 total…

…showed last 75 words of 3969 total…The concentration of water in potato is high than that in these concentration. Therefore water leaves the potato cell to reach equilibrium point with solution of sucrose. As water leaves the cell, the mass of the potato decreases more than the previous concentration. At 0.8M the mass decrease is -2.94% with compared to 1.0M which has high decrease of -7.91%.As in high concentration (at 1.0),few water molecules are present than in the molar concentration of 0.8M. .
