A.
Gradient of DPD
B.
Tension due to transpiration pull
Answer
C.
Root pressure
D.
The utilisation of metabolic energy

Answer: Option B

Solution

Answer: Option B
Solution:
In passive water absorption, water is absorbed through Tension due to transpiration pull.
Passive absorption is absorption by the pull from transpiration without the active involvement of the root cells.
The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.
