Source of Fluid pH (mean) Standard Error of Mean (SEM) Stroma 8.2 0.75 Inner compartment of thylakoid 5.6 0.35 Make a prediction for the pH levels in the plant if it closes its stomata for an extended period of time. Justify your predictions.
The osmotic potential of the plant cell is -0.1 MPa and it is placed in an 9 mM sorbitol solution (21 °C). Calculate the turgor pressure of the cell when the water potential of the cell has equilibrated to the same as that of the solution.

Consider a soil with the following properties: The water content at the permanent wilting point is 0 = 5 Vol.% The actual plant available water accounts for 3 Vol.% The water content at saturation is 0,-38 Vol.% The water content at a suction of 10 cm is 35 Vol.% a) What is the field capacity of your soil? State the calculation, not only the result. b) What matric potential (suction) values do you assume for the wilting point and field capacity of your soil?
Water potential a) The value for Ψ in root tissue was found to be -3.3 bars. If you take the root tissue and place it in a 0.1 M solution of sucrose at 20°C in an open beaker, what is the Ψ of the solution, and in which direction would the net flow of water be? b) NaCl dissociates into 2 particles in water: Na+ and Cl-. If the solution in question 4 contained 0.1M NaCl instead of 0.1M sucrose, what is the Ψ of the solution, and in which direction would the net flow of water be? c) A plant cell with a Ψs of -7.5 bars keeps a constant volume when immersed in an open-beaker solution that has a Ψs of -4 bars. What is the cell’s ΨP?
Some seeds (tomato, for example) had been germinated and the seedling grew for 2 weeks in soil, where the soil water potential was maintained at -0.2 bars. The plants were then divided into 5 groups and each group subjected to a different soil water potential as follows: Group 1: 0 bars Group 2: -0.03 bars Group 3: -0.2 bars Group 4: -3.0 bars Group 5: -5.0 bars At the end of three weeks at these various soil water potentials, the plants that would have made the least growth would be expected in which group?

You place a flaccid plant cell (Ψ = -0.7 MPa) into an environment (beaker) of pure (deionized) water (Ψ = 0 MPa). Compare the initial conditions of the flaccid cell and the environment (beaker of pure water) in terms of: G) Predict the direction of water movement (into the cell, out of the cell, or no net movement) H) Predict the change in turgor pressor of the cell (increase turgor pressure or decrease turgor pressure) I) Predict the fate of the cell (plasmolyzed, turgid, or lysed)
