Question

(A)Diffusion does not meet the high energy requirements of the multicellular organisms.(R)Diffusion is a fast process but only occurs at the surface of the body.

Answer 1

both the assertion and reason are correct but the reason is not the correct explanation of the assertion.

Explanation:

• Diffusion can be defined as the movement of the particle from the region of the higher concentration to the region of the lower concentration by the movement of the solute particle.

• Thus diffusion is a very fast process. The energy requirement of diffusion is very low as compared to Osmosis or active transportation. diffusion takes place fastest in case of gases and slower in liquids and slowest in solids
