Q. Physiological demonstration of osmosis is carried out by :

(a) Potometer

(b) Bell jar experiment

(c) Thistle funnel whose mouth is tied with egg membrane.

(d) Thistle funnel whose mouth is tied with paper.

Solution :

Correct option : C 
Osmosis is the process of movement of solute from lower concentration to higher concentration through a semi-permeable membrane. For the demonstration of osmosis, many experiments are popular including the transfer along the solute gradient. So, the correct answer is ‘Thistle funnel whose mouth is tied with egg membrane’.
