Best Answer

Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:

  • a large surface area
  • a thin permeable surface
  • a moist exchange surface.
