3. Predict the direction in which water will flow given the following information: A student calculates that the water potential of a solution in a dialysis bag is equal to -6.25 bars (4,= -6.25, .= 0). The water potential of a solution surrounding the bag is -3.25 bars (#, - -3.25, ',=0). In which direction will water flow? Justify your answer. 4. If a plant cell's water potential is lower than its surrounding environment and if pressure is equal to zero, is the cell hypertonic (in terms of solute concentration) or hypotonic to its environment? Will the cell gain or lose water? Justify your answer. 5. A plant cell with a pressure potential of $ bars and an osmotic potential of -9 bars is in equilibrium with a surrounding solution which is open to the air. What is the water potential of the surrounding solution? 6. What effect does adding solute have on the solute potential component (Y',) of that solution? Justify your answer. 7. Calculate the solute potential of a 1.0 M sucrose solution at 25 oC and standard atmospheric conditions. 8. Calculate the solute potential of a 0.1 M NaCl solution at 22 C
