Solution

The correct option is C Solvent only
Semi permeable membrane allows movement of solvent molecules only into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. The phenomenon is called Osmosis.

Q. Read the given statements and select the correct ones.
(i) A membrane which permits the passage of pure solvent molecules to pass through it and not the solute particles is called semi-permeable.
(ii) A membrane which allows some substances to pass through it more readily than others is known as selectively/differentially permeable.
(iii) All living biological membranes are perfectly semipermeable.

The phenomenon of flow of solvent molecules through a semi permeable membrane from pure solvent to solution is called

The most appropriate characteristic of a semi-permeable membrane is that

(a) it has minute pores.
(b) it has no pores.

(d) it allows a solvent to pass through freely but prevents the passage of the solute.
