Concept explainers
To determine: Whether water will flow by osmosis from one plant cell with water potential of -1.5MPa to another plant cell with water potential of -1.8MPa.
Introduction: Water is the most crucial factor for a plant to perform its normal cellular functions. The water is absorbed by the roots. The movement of water from the roots to the leaves can be explained using cohesion tension theory of water transport. The water movement from the roots to the vascular tube (xylem) is facilitated by osmosis. Water potential plays an important role in understanding plant physiology because it helps to measure a cell’s ability to absorb water by osmosis.
To determine: The direction of water flow when a plant cell with a water potential water potential of -1.5MPa to another plant cell with water potential of -1.8MPa.

- 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.arrow_forwardIf you place a flaccid plant cell with ΨS = -0.4 MPa in pure water, which of the following will occur? A. Water will not enter the cell because the flaccid cell has solutes and low water potential. B. Water enters the cell because the flaccid cell has solutes and low water potential. C. Water enters the cell because the flaccid cell has solutes and high water potential. D. Water will not enter the cell because the flaccid cell has solutes and high water potential.arrow_forwardA of Y, = 0.2 Y, = -0.7 Y, = 0.8 Y, = -0.9 || Based on this diagram of two plant cells, what direction do you expect water to move?
