Why do the roots of mangrove trees grow upward?
The saline marshy soil lacks oxygen. Normally, soil on land has gaps through which the roots take in oxygen, but in marshy soil, these gaps are filled with water. Therefore, to breathe, the roots grow above ground level.

Pneumatophores, commonly found in mangrove species that grow in saline mud flats, are lateral roots that grow upward out of the mud and water to function as the site of oxygen intake for the submerged primary root system. The roots of certain parasitic plants are…
What type of roots do mangrove have that grow above the muddy water?
Although the black mangrove does not have prop roots, small air roots can be seen extending vertically from the soils surrounding the trunk. These air roots, called pneumatophores, extend upward from the underground roots above the soil surface.
How do mangrove trees respire?
In addition to providing structural support, aerial roots play an important part in providing oxygen for respiration. Oxygen enters a mangrove through lenticels, thousands of cell-sized breathing pores in the bark and roots. Lenticels close tightly during high tide, thus preventing mangroves from drowning.

1 : a muscular gas-containing sac that serves as a float on a siphonophore colony. 2 : a usually partially exposed root of a wetland plant (such as a mangrove) that functions especially in the intake of oxygen from the atmosphere.
How do pneumatophores work?
Pneumatophores are specialized roots that act like snorkels when partially flooded and have pores called lenticels that cover their surface where oxygen exchange occurs. The lenticels contain substances that are hydrophobic, meaning they repel water, so when submerged, water cannot flood into the root.

Do pneumatophores absorb water?
They are used for breathing in air and extracting nutrients from the water. The roots are full of small air spaces that allow the tree to take in oxygen from the air and distribute it throughout the tree. The roots also absorb nutrients from the water, which helps to support the mangroves in nutrient-poor environments.
Why do pneumatophores need oxygen?
All Answers (5) As mangroves grow in muddy soil which have negligible oxygen due to which they develop pneumatophores to supply oxygen to the root system. the aerial parts like stomata in the leaves cannot compensate it to the root system.
