Pneumatophores of mangrove plant Pneumatophores differentiate the black mangrove and grey mangrove from other mangrove species. Fishers in some areas of Southeast Asia make corks for fishing nets by shaping the pneumatophores of mangrove apples ( Sonneratia caseolaris ) into small floats.
They function to help the colonies maintain their orientation in water. [6] In the Cystonectae subgroup, the pneumatophores have an additional function of assisting with flotation of the organisms. [6] The siphonophores exhibiting the feature develop the structure in early larval development via invaginations of the flattened planula structure. [6]

In botany, pneumatodes are air-containing structures in plant roots. [1] Their function is to allow gaseous exchange in root tissues. This can be beneficial to semi-aquatic plants, such as neo-tropical palms. [2]
Anaerobic bacteria liberate nitrogen gas, soluble ferrum (iron), inorganic phosphates, sulfides, and methane, which make the soil much less nutritious. [citation needed] Pneumatophores (aerial roots) allow mangroves to absorb gases directly from the atmosphere, and other nutrients such as iron, from the inhospitable soil. Mangroves store gases ...
Vertical roots called pneumatophores project from the mud, thus the term "pencil roots". These are used in gas exchange as very little oxygen is available in the mud. The flowers are fragrant and rich in nectar, and are pollinated by insects. The embryos exhibit cryptovivipary, a process where they start to develop before the seed is shed, but ...
Nevertheless, extracts are made from the pneumatophores which are used in the manufacture of perfume. Parts of the tree are eaten; the root tips are relished in Thailand; the bark supplies a spice and the young shoots are boiled and served as a vegetable. [3] In Maldives the propagules are boiled and eaten as a vegetable in the islands where it ...
In oxygen deprived conditions, making respiration a daily challenge, different species may possess specialized structures where lenticels can be found. For example, in a common mangrove species , lenticels appear on pneumatophores (specialized roots ), where the parenchyma cells that connect to the aerenchyma structure increase in size and go ...
