Give scientific reasons: The root of the $Rhizophora$ plant is called a breathing root.

(N/A) $\rightarrow$ Plants that grow in muddy and saline soil along the seashore are known as mangroves. $Rhizophora$ is a classic example of a mangrove plant.
In such environments,the soil is waterlogged and saline,which significantly reduces the availability of oxygen for the root system.
To overcome this oxygen deficiency,$Rhizophora$ develops specialized roots that grow vertically upwards,against the direction of gravity (negatively geotropic),emerging above the soil surface.
These roots,known as pneumatophores or breathing roots,contain small pores called lenticels.
These pores facilitate the exchange of gases,allowing the plant to absorb $O_2$ directly from the atmosphere to support the metabolic activities of the root system.
