Q675
The water from the soil enters into root hairs on account of
A.
Turgor pressure
B.
Suction pressure
AnswerC.
Osmotic pressure
D.
Hydric pressure
Answer: Option B
Solution
Answer: Option B
Solution:
The water from the soil enters into root hairs on account of Suction pressure.Suction pressure is also called Diffusion Pressure Deficit. If some solute is dissolved in a solvent, its diffusion pressure decreases.
It is DPD that tends to equate and represent the water-absorbing ability of a cell, it is also called suction force (SF) or suction pressure (SP). The actual pressure with which a cell absorbs water is called "suction pressure".
