The value for  Ψ\Psi  in root tissue was found to be -3.3 bars.  If you take th root tissue and place it in a 0.1 M solutin of sucrose at 20 °\degree C in an open beaker, what is the  Ψ\Psi  of the solution, and in which direction would the net flow of water be?

 Ψs\Psi s  = -3.3, net flow into the root

 Ψs\Psi s  = 3.3, net flow out of the root (into the solution)

 Ψs\Psi s  = -2.43, net flow into the root

 Ψs\Psi s  = 2.43, net flow out of the root (into the solution)

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\Psi  of the solution, and in which direction would the net flow of water be?

-3.3 bars, net flow out of the root (into the solution)

3.3 bars, net flow into the root

-4.87 bars, net flow out of the root (into the solution)
