Question

Value of osmotic potential $\left(\pi \right)$ and pressure potential (p) of cells a, b, c, d are given:

Cell	$\pi$	p
a	1.0	0.5
b	0.6	0.3
c	1.2	0.6
d	0.8	0.4

Identify the correct sequence for movement of water.

• A. b $⟶$ c $⟶$ d $⟶$ a
• B. c $⟶$ b $⟶$ a $⟶$ d
• C. d $⟶$ c $⟶$ a $⟶$ b
• D. b $⟶$ d $⟶$ a $⟶$ c

Answer 1

The correct option is D b $⟶$ d $⟶$ a $⟶$ c

Osmotic pressure is the movement of a solute particle from low concentration to high concentration through a semi-permeable membrane.

So, the water will move from a higher concentration to a lower concentration.

So, the correct option is 'b,d,a,c'.
