Explanation;

  • Diffusion is a type of passive transport that involves the movement of particles from a region of high concentration to a region of low concentration.
  • Diffusion takes place in liquids and gases, since their particles can move randomly from one region to another.
  • Therefore, diffusion results from the random movement of particles in which the net movement is down the concentration gradient  that is, from a region of high concentration to a region of low concentration.
