Question

Which one is not connected with transport across the cell membrane?

• A. Osmosis
• B. Active transport
• C. Diffusion
• D. Surface tension

Answer 1

The correct option is D Surface tension

(A) Osmosis is the movement of the solute molecule from lower concentration to higher concentration through a semi-permeable membrane.

(B) Active transport is the transport of molecules which is energy dependent.

(C) Diffusion is the movement of molecules from a higher concentration to lower concentration.

(D) Surface Tension is the elastic tendency of a fluid surface to cover the least possible surface area.

So, the correct answer is 'Surface Tension'.
