Title: AP Biology Lab #1: Diffusion and Osmosis Graph 1.3 Analysis: Exercise D) Water Potential from Experimental Data: Group: -1(0.17 mole / liter)(0.0831 liter bar / mole °K)(295°K) = -4.1675 bars Class: -1(0.19 mole / liter)(0.0831 liter bar / mole °K)(295°K) = -4.6578 bars 1) The water potential of the potato core after dehydrating will decrease because the water within the potato would evaporate and therefore lower the water potential. 2) The solute concentration of the plant cell is hypertonic because the solute concentration is higher than the water concentration. Because of this, water will diffuse into the cell to reach dynamic equilibrium. 3) The pressure potential of the system is equal to 0. 4) The water potential is greater in the dialysis bag . 5) Water will diffuse out of the bag since the water potential is higher in the bag and water moves from areas of

Unformatted text preview: higher water potential to areas of lower water potential. 7) b : Molar Concentration of Solutes in the Zucchini: 0.35 mole / liter 8) a) Solute Potential = -1(0.35 mole / liter)(0.0831 liter bar / mole °K)(295°K) = -8.5801 bars b) Water Potential = 0 + -8.5801 = -8.5801 bars 9) Adding solute to a solution increases solute potential because the solute concentration increases. 10) a) Distilled Water will have a higher concentration of water molecules. b) Distilled Water will have a higher water potential. c) The red blood cells would increase in size because water is moving from the area of higher water potential (the distilled water) to the area of lower water potential (the red blood cells) until equilibrium is reached....
