Solution

The correct option is B Due to increased osmotic pressure in the root
Cells of the root are in close contact with soil and actively take up ions. The ion concentration increases inside the root and hence, osmotic pressure increases the movement of water from the soil into the root, which occurs continuously.

Q. Transpiration leads to an increase in the osmotic pressure in the leaf cells.

Absorption of minerals by the epidermal cells of root and root hair causes the water to enter from surrounding soil into roots. It further reaches the root xylem. Thus, due to a continuous uptake of water by root cells, a water pressure is created in the root xylem. This pressure is called as________

Q. The osmotic potential and pressure potential of three cells (A,B,C) located in different parts of an actively transpiring plant are given below.

Cell	Osmotic potential (mpa)	Pressure potential (mpa)
A	-0.87	0.44
B	-0.92	0.34
C	-0.68	0.27

Identify these three cells as root hair, root cortical and leaf mesophyll cells respectively.

Q. In which condition the turgor pressure of the cell becomes equal to the osmotic pressure?
