What is the role of pressure potential in water transport in plants?
What is the role of pressure potential in water transport in plants?
To increase water absorption by plant cells
To regulate water transport up a stem
To decrease water transport in the xylem
None of the above
Solution
Pressure potential, denoted as Ψp, plays a major role in regulating water transport up a stem in plants. Negative potential or tension in the water column in the xylem helps to move water up the stem.
