Root hair absorb water from the soil on account of

Options

A. Turgor pressure
B. Osmotic pressure
C. Suction pressure
D. Root pressure

Answer

C

Explanation

The osmotic absorption of root hair depend on suction pressure osmotic pressure of cell sap of root hairs is usually higher than the OP of the soil water. Therefore the diffusion pressure deficit and suction pressure in the root hairs become higher and water from the cell wall enter into them through plasma membrane by osmotic diffusion.
