Question

mangrove trees respire through?​

Answer 1

Answer:

For this purpose, mangrove species have specialized above ground roots called breathing roots or pneumatophores. In some species, these roots are pencil sized and peg like whereas in some other species they look like a knee. These roots have numerous pores through which oxygen enters into the underground tissues.

Explanation:

Although they are land plants, they grow in saltwater and their roots are buried in thick mud that contains little oxygen. In order to breathe, the roots send up spikes that rise into the air above the level of the mud. When the tide is out, these spikes can exchange oxygen and expel carbon dioxide into the air.
