Solution

$\rightarrow$ The plant that grows in muddy and salty soil at sea shore is called Mangrove. Teevar and Rhizophora are its examples. The water has less capacity to absorb oxygen due to mud and salty water. So its root system does not get sufficient oxygen. So to obtain oxygen from local roots are developed in opposite direction of gravity, towards light in the soil. These roots are porous, that absorb $\mathrm{O}_{2}$ from the atmosphere and provide to root system. Such roots are called breathing roots.

Roots obtain oxygen from air in the soil for respiration. In the absence or deficiency of $O_{2}$, root growth is restricted or completely stopped. How do the plants growing in marsh lands or swamps obtain their $\mathrm{O}_{2}$ required for root respiration?
