What would ψw, ψs, and ψp of the cell in figure 36.5a be at equilibrium if it had been placed in a solution with a ψs of −0.5 MPa?
To determine: The
Introduction: Water potential defines the ability of water to move from one are to another through osmosis under the influence of gravity, pressure and capillary action. Water potential constitutes of pressure potential and solute potential.
Explanation of Solution
The solute potential of the solution and the cell before equilibrium is -0.5 MPa and -0.2 MPa respectively. The solution has a higher concentration of solute than the cell and hence, water will leave the cell, causing the cell to plasmolyze. Initially, the turgor pressure of the cell and the solution
Thus, at equilibrium,

- Which setup would exhibit the greater osmotic pressure: a cell with a cytosol concentration of 0.9% immersed in (a) pure water or (b) a 0.2% NaCl solution? Explain.arrow_forwardIf a plant cell immersed in distilled water has a ΨS of-0.7 MPa and a Ψ of 0 MPa, what is the cell’s ΨP? If youput it in an open beaker of solution that has a Ψ of-0.4 MPa, what would be its ΨP at equilibrium?arrow_forwardAnthocyanins are another type of plant pigment that are purple or red. Say you run a chromatography experiment using the same setup as you did in this lab, and you find that anthocyanins do not move from the line of origin. Assuming the solvent traveled the same distance as in your experiment (D in Table 1 above), what is the Rf value of anthocyanin?arrow_forward
- using the cell potential table found in the Reference Material, why do you get holes in your aluminum foil if you use it to cover lasagna in a steel pan? Hint: Steel is made up of mostly iron and lasagna serves as an acidic medium.arrow_forwardAssume the diameter of the field of vision in your microscope is 1.75mm under low pressure. If one bacillus is 5um, how many bacillus cell could fit end to end across the field. How many 7um yeast cells could fit across the field?arrow_forwardGiven the following compositional assessment of a cell membrane, describe from ER to cell membrane how this composition was synthesized and why it is asymmetric?

What are the consequencesof these differences in surface-to-volume ratio for cell function?arrow_forwardIf the potato cells were hypotonic to the surrounding solution, the surrounding solution itself would be what to the potato cells (hypertonic, hypotonic, or isotonic)?arrow_forwardTwo wavelengths of light strike a living cell, one has a wavelength of 12 nm, and one has a wavelength 700 nm. Based on the electromagnetic spectrum, which one would be considered more dangerous to the cell? Why? (note: 1 m = 109 nm)arrow_forward
