Summary Introduction
Introduction: Flaccidity is the condition of a plant cell in which its plasma membrane is not tightly pressed against its cell wall. This condition is observed when the plant is placed in an isotonic solution where the inside and outside concentration of the solutes remains constant. In this state, the plants look weak, soft, and lack vigor.

If 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.
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.
You place a flaccid plant cell (Ψ = -0.7 MPa) into an environment (beaker) of sucrose solution (Ψ = -0.9 MPa). Compare the initial conditions of the flaccid cell and the environment (beaker of sucrose solution) in terms of:
A) Water potential (high or low) of the environment
B) Solute concentration (high or low) of the environment
C) Tonicity (hypertonic, hypotonic, or isotonic) of the environment
D) Water potential (high or low) of the cell E) Solute concentration (high or low) of the cell
F) Tonicity (hypertonic, hypotonic, or isotonic) of the cell G) Predict the direction of water movement (into the cell, out of the cell, or no net movement)
H) Predict the change in turgor pressor of the cell (increase turgor pressure or decrease turgor pressure)
I) Predict the fate of the cell (plasmolyzed, turgid, or lysed)
