Question

Osmosis and diffusion differ, that osmosis is one-way traffic and diffusion is a two-way traffic.

• A. True
• B. False

Answer 1

The correct option is A True

Osmosis is a kind of diffusion in which water molecules diffuse through a semipermeable membrane down the concentration gradient.

Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration.

In osmosis, only water molecules can pass across the membrane whereas, in diffusion, both solutes and solvent (water) molecules can pass across the membrane. Hence, osmosis is one-way traffic and diffusion is a two-way traffic.

Thus, the statement given in the question is correct.

So, the correct answer is 'True'.
