What are the special characteristics of mangrove plants to the high-salt intertidal environment?

Mangrove plants play an important role in regulating climate and preventing coastal erosion in the intertidal zone with high salinity, and at the same time, mangrove plants will form a unique marine woodland at the seaside.

Mangrove plants play an important role in biogeochemical cycle of biogenic elements. Phosphorus is a basic and important element in estuarine environment, an important component of nucleic acid, membrane lipid and energy metabolism, and is very important for the growth and development of mangrove plants growing in intertidal zone.

Features:

The cells of mangrove plants can filter high salinity seawater into fresh water, and then excrete salt through metabolism, which is a bit like sweating. Sometimes the leaves of mangrove plants will appear salt crystallization, which is the result of this process.

Moreover, in order to survive, mangroves have evolved a very unique way of reproduction-viviparous. The seeds of mangrove plants can't germinate and grow directly in seawater, so the seeds will develop on the trees first, grow into seedlings, fall off the trees and grow on their own in seawater.
