How do mangroves survive in salty water?

Mangroves survive in salty water by using specialised adaptations such as salt-excreting leaves and filtration systems in their roots. Some mangroves excrete excess salt through glands on their leaves, while others store salt in older leaves that are eventually shed. Their roots also prevent salt uptake by filtering seawater as it is absorbed. Mangroves are vital ecosystems, protecting coastlines from erosion and supporting diverse marine life, despite thriving in challenging environments.
