1. Why are the roots of mangroves called breathing roots?
The mangrove soil is anaerobic, that is, oxygen poor as well as unstable and mangroves have root adaptations such as breathing roots (or aerial roots) to cope with these conditions.
A mangrove is a small tree or shrub which grows in brackish water or coastal saline. Mangroves have roots that grow above the soil. Underground tissues of mangrove requires oxygen for breathing and in mangrove environs, oxygen in the soil is nil or very limited.
This requires mangrove root system to gather oxygen from the air or atmosphere. Mangrove have specialised roots that grow above the ground and are called as pneumatophores or breathing (aerial) roots.
These breathing or aerial roots have pores by way of which oxygen go into the tissues that grows underground .
