How does water get into a coconut?

Water enters a coconut through the palm tree’s root system via natural osmosis. Coconut palms absorb groundwater from the soil. This water travels upward through the trunk via vascular transport tissues called xylem, carrying along dissolved essential soil minerals such as potassium, magnesium, and sodium.

As the palm tree fruits, this mineral-rich water is routed directly into the interior cavity of the developing young coconut. In early growth stages, the liquid serves as a nutrient storehouse for the growing seed. Over several months, cellular processes deposit fat along the inner wall to form solid white coconut meat. As the coconut matures, liquid converts to meat, leaving less water inside.
