and QUESTION 12 1 points Save Answ f a plant cell with a solute potential of 0.2 MPa is placed in a beaker of pure water at equlibriu t will have a pressure potential of +0.2 MPa because the cell wall preven with a solute potential of-0.3 MPa that is open to the atmosphere (draw a picture if it helps youj. ts cell expansion. If that cell is then placed in a solution Water will flow out of the cell Water will flow into the cell There will be no net movement of water °Solutes will move out of the cell The cell will explode QUESTION 13 1 points save The process where water is "pulled" up through the xylem and is lost through leaves is called root pressure O transpiration capillary action adhesion of water molecules cohesion of water moleculesExplanation / Answer
12. water potential is positive now as the pressure potential is positive, and hence after being placed into a solution with-0.3MPa the water will flow out of the cell.
Water potential= pressure potential+solute potential
13. Transpiration. It is the process that is driven by evaporation of water,a negative pull rather than positive push. The water rises in the xylem as it is lost at the leaf surface by evaporation. This process is termed as transpiration
