Question

In trees at a height of 75 meters, the magnitude of gravitational component of water potential in leaves is:

• A. - 0.25 MPa
• B. - 0.50 MPa
• C. - 0.75 MPa
• D. - 1.00 MPa

Hint:

To quickly calculate gravitational water potential, remember the direct conversion factor:
$\Psi_g$ changes by $0.01 \text{ MPa}$ for every $1 \text{ meter}$ of height.
Simply multiply the height in meters by $0.01$ to get the value in MPa.

Answer 1

The Correct Option is C
