Question

The movement of molecules from their higher concentration to lower concentration is called as

• A. Osmosis
• B. Diffusion
• C. Diffusion pressure deficit
• D. Diffusion pressure gradient

Answer 1

Answer: (B)

Diffusion

Diffusion refers to the process by which molecules intermingle as a result of their kinetic energy of random motion. It is the net movement of molecules or atoms from a region of high concentration to a region of low concentration. This is also referred to as the movement of a substance down a concentration gradient.

So, the correct answer is option B.
