2.) Calculate Vw for a 0.2 Molar NaCl solution (not a cell) at 20C. Note that you are working with a SALT solution that ionizes now - think about how that will affect Cs as you calculate ww. The following constants may be helpful to you. R = 8.32 1 mol K T = 273K - C 1 osmolal = 1 x 102 mol m H.O J m = Pa MPa = Pax 106 w for a 0.2 M NaCl solution = _MPa (1 pt) 2.) Plant tissue with a Ww=-0.7 MPa is placed in a solution with Yw=-0.8 MPa Will the turgor of the cells in the tissue increase or decrease? (Ipt) Calculate w for the tissue when it reaches equilibrium with the solution? NOTE that equilibrium will be reached when yw of the cell = w of the solution. Assume for this question that the amount of water that moves between the two is not significant enough to change Ys for the cell or the solution). w for the plant tissue will be MPa (1 pt) 3.) If a flaccid cell with a Ps= -0.9 MPa is placed in a 0.3 M sucrose solution (it would be the same w as your cell at incipient plasmolysis.), Will water move - into or out of the cell? (1 pt.) After equilibrium is reached w for the cell = MPa (1pt) After equilibrium is reached p for the cell = MPa (1 pts) 4.) A turgid plant cell where Ws=-1.0 MPa and p = 0.4 MPa is placed in a 0.2 M NaCl solution Which way does water move into or out of the cell? (1 pt) After equilibrium is reached Yp for the cell MPa (1 pts)
