Mangrove pneumatophore roots absorb carbon dioxide from the air.
<h3>WHAT ARE PNEUMATOPHORES?</h3>
Pneumatophores, also called breathing roots, are types of roots possessed by mangrove plants.
Mangrove plants are adapted to swampy conditions, hence, must possess adaptational features that ensures their survival.
Pneumatophores help the mangrove plants to exchange gases like carbon dioxide and oxygen in the atmosphere.
Therefore, mangrove pneumatophore roots absorb carbon dioxide from the air.

Elephant tusks are considered to be enlarged and elongated incisors. One third of the tusk is usually located deep inside the elephant's head while the remaining two third of the tusk can be seen outside.
