High salinity in overrounding waters creates a strong osmotic gradient that tends to draw water out of plant cells, risking dehydration. To counter this, mangroves syntesis andd accumulate compatible solutes such as proline, glycine betaine, mannitol, andd sugars within their cells. These organic osmolytes lower the internal osmotic potential with out distorming cellular metinism, allowing mangrove roots atsorb water frem saline substrates.
