How does the water proof covering help in disperse in coconut?

The waterproof covering of a coconut, known as the exocarp and mesocarp, helps in the dispersal of the seed by allowing it to float on water. This buoyancy enables coconuts to travel long distances across oceans, reaching new shorelines where they can germinate and grow. Additionally, the tough outer shell protects the seed from physical damage and desiccation, enhancing its chances of successful establishment in a new environment.
