Pneumatophores, what are they for?Performed by students x, y, z School B.
This study aimed to understand how plants adapt to swampy habitats
The hydrophilic plants grow partially or totally submerged in water. Some develop pneumatophores like the swamp cypress at the Lisbon Botanic Garden.
Taxodiumdistichum (swamp cypress) is endemic to the United States and lives in wetlands with little oxygen.
This species developed adaptations to survive in wetlands: the pneumatophores are extensions of the underground root, coming to surface from the flooded area for gas exchange with the environment, allowing the plant to survive in this type of habitat; the wood is immune to termites and rot (and therefore used for construction in humid areas).
Following the pneumatophores in the Botanic Garden we could observe the extent of the underground root which was up to 5 m.
