Answer:

Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.

Respiratory surfaces in both human beings and plants have several characteristics that are peculiar and similar to each other. There are some requirements to be met for gaseous exchange to occur.

Two characteristics that the respiratory surface used for gaseous exchange in human beings has in common with the respiratory surface used in flowering plants include ---

1.  Respiratory surface must be thin and allow for rapid diffusion.

2. These surfaces must be in contact with air or fluid.

  • Respiratory surfaces in plant living cells in the stem are organized in thin layers close to the surface.
  • Their loose packing ensures air spaces where they are in close contact with the  airflow either in or out.
  • In humans, the respiratory surface is thin allowing for rapid diffusion of oxygen in and CO₂ out.
  • They are also always in contact with the blood
