To facilitate gaseous exchange, breathing roots have

Breathing roots are specialized roots in certain plants that grow in waterlogged soils or submerged in water. They have special adaptations to facilitate gaseous exchange, which is the process of taking in oxygen and releasing carbon dioxide. The adaptations include the presence of small openings called lenticels, which are pores on the surface of the roots that allow for the exchange of gases. The lenticels are surrounded by spongy tissue that is rich in air spaces. This allows the roots to absorb oxygen from the air and release carbon dioxide produced during respiration. Stomata, cuticle, and mitochondria are not adaptations found in breathing roots.
