Question

Which of the following is true about diffusion and osmosis? A) Both diffusion and osmosis requires energy taken in for net movement of particles. B) Both diffusion and osmosis refers to movement of water molecules. C) Both diffusion and osmosis involves movement of particles down a concentration gradient. D) Both diffusion and osmosis only takes place when particles are in liquid state.

Answer 1

Answer:C

Explanation:A) both diffusion and osmosis does not need energy.

B)diffusion refers to movement of molecules from higher concentrations to lower concentrations. But osmosis is the movement of water molecules from higher concentrations to lower concentrations through a semipermeable membrane.

D) diffusion in any phase

Osmosis I liquid phase.

Hope it helps

Answer 2

C) Both diffusion & osmosis involves movement the particles down a concentration gradient.

• Both the diffusion & the osmosis does not requires the energy taken in for a net movement of the particles.

Hence, option A is an incorrect.

• Diffusion refers to the movement of  those molecules from the higher concentrations to a lower concentrations where-as the osmosis is movement of water molecules from the higher concentrations to the lower concentrations through the semipermeable membrane.

Hence, option B is also incorrect.

• Diffusion takes place in the any state & osmosis only takes place when particles are in the liquid state.

Hence, option D is also incorrect.

Hence, The option C is the correct answer .
