Question

• Discuss Diffusion vs. Osmosis give example

Answer 1

Diffusion refers to the movement of solute and solvent molecules from high concentration to their low concentration across the membrane. It depends upon concentration gradient, temperature, pressure, wall permeability etc. Example: movement of ions across plasma membrane.

Osmosis: It specifically refers to the movement of water molecules from low solute concentration medium to high solute concentration medium through the semi permeable membrane. For example. Movement of water in roots from the soil.
