Question

Untrue about diffusion
(A) It is a passive process
(B) It is a slow process
(C) It does not require energy
(D) It depends on a living system​

Answer 1

Diffusion depends on a living system is untrue about the diffusion. (Option D)

• There are four statements mentioned in the question about the diffusion process.
• Diffusion is a passive mode of transportation, so the first statement is true.
• Diffusion occurs very slowly, so the second statement is true.
• Diffusion does not need any kind of external energy input, that's why the third statement is also true.
• But, there is no such requirements of any living system for the occurence of the diffusion.
• That's why, the fourth statement is untrue.

Answer 2

Untrue about Diffusion is option D) It depends on a living system.

Explanation:

1. Diffusion is a intermixing of the substances due to the movement of the particles from high concentrated region to low concentration region.

2. Diffusion is a passive process of transport  which does not require energy .

3. Its a slow process and hence  diffusion does not depend on living system as It can occur in non-living systems as well.
