In each problem below draw an arrow showing which way water will move/flow.
Is the solution hypertonic, hypotonic or isotonic?
Consider a plant cell. The value for solute concentration in a plant cell is -0.12 MPa and the turgor pressure is 0.12 MPa.
1- What is the water potential in this plant cell?
2- If this plant cell were placed in a solution with water potential of -0.1 MPa, what would happen to the cell? (Hint: explain where the water goes and what that does to the cell).
. DRAW IT An artificial “cell” consisting of an aqueous solutionenclosed in a selectively permeable membrane is immersed ina beaker containing a different solution, the “environment,”as shown in the accompanying diagram. The membrane ispermeable to water and to the simple sugars glucose and fructosebut impermeable to the disaccharide sucrose.(a) Draw solid arrows to indicate the net movement of solutesinto and/or out of the cell.(b) Is the solution outside the cell isotonic, hypotonic, orhypertonic?(c) Draw a dashed arrow to show the net osmosis, if any.
(d) Will the artificial cell becomemore flaccid,more turgid,or stay the same?(e) Eventually, willthe two solutionshave the same ordifferent soluteconcentrations?
