Water enters from soil into the root hairs due to
Options
(a) turgor pressure of root hair
(b) osmotic pressure of root hair
(c) suction pressure
(d) diffusion pressure
Correct Answer:
suction pressure
Explanation:
D.P.D. (diffusion pressure deficity) is the amount by which the diffusion pressure of a solution is lower than that of its pure solvent. The DPD of a cell denotes the net pressure that causes water to enter cell. DPD = OP – WP and since WP = TP thus DPD = OP – TP. D.P.D is also known as suction pressure.
