What organ found in mangrove roots allows diffusion and transport of oxygen to underground root systems in the anaerobic mud?

Lenticels found in mangrove roots allows diffusion and transport of oxygen to underground root systems in the anaerobic mud.

Explanation:

Lenticels are the small pores located on the aerial roots responsible for the gaseous exchange ( intake of oxygen ).

The Mangrove species contain a very large number of lenticels surround their roots and stems helping in the gaseous exchange ( respiration ) even in the anaerobic mud as he lenticels are surrounded by tide, as the root pressure begins to drop. When the tide goes down , air is again sucked in the aerenchym.

As in the anaerobic mud , their specialized roots allow mangroves to grow in anaerobic situations .
