Question

Please show work! Thank you -16. The value for in root tissue is-15 MPa. The root tissue is placed in .1 M sucrose solution with a ps of -25 MPa. The sucrose solution is in an open container. Which of the following is TRUE? A. Water will move by osmosis from the root tissue into the sucrose solution. B. Water will move by osmosis from the sucrose solution into the root tissue. C. There will be not net movement of water because the cell and solution are at equilibrium. D. Water will move by active transport from the root tissue into the sucrose solution. 17. Assuming that the root tissue described above reaches equilibrium at a of-25 MPa, and the 4p of the root tissue is measured at.6 MPa. What is the ys? A. -.15 MPa B. -.85 MPa C. .35 MPa D. -.4 MPa

Explanation / Answer

Answer: A (water will move by osmosis from the root tissue to the sucrose solution)

As we know Water potential has never a positive value and its maximum value is zero and pure water has this value. More the solutes in water more negative will be its value. Therefore, concentrated solution (hypertonic) has more negative value and hypotonic solution has lesser negative value.

In the given question, sucrose solution has more negative value (0.25MPa) compare to that in the root tissue (0.15MPa). Therefore, the solution in root tip is hypotonic compared to outside sucrose solution, therefore, water will move out of the root tissue by osmosis
