What is the function of Pneumatophore?
Pneumatophores are lateral roots that extend out of the surface of the water and facilitate the exchange of oxygen and carbon dioxide for the roots submerged in water. They are specialized aerial root structures present in plants where the oxygen required for normal respiration of roots is inadequate.
