Eli5 : How water gets accumulated in coconuts? And why its sweet in taste even though the tree grows in salty water areas…??
In: 6
Being in “salty water areas” doesn’t mean plants use salt water, they are resistant to it, more than other plants, but they still need fresh water.
Water is accumulated the same way with every tree it gets sucked up from the ground, coconut tree store the water in it because it is the fruit/seed of the tree, it needs more nutrients
The sweetness come from the sugar from photosynthesis. It is how plants make energy, taking in sunlight and CO2 and converting it to oxygen and sugars.
Water doesn’t “accumulate” in coconuts, it’s part of the the coconut. That’s like asking how the juice in an orange “accumulates” in the orange. And I’m not sure why you think coconut palms grown in salty water areas – they grow everywhere, and even if they did, that that’s not how it works. Anyway, coconut water is sweet because it has naturally occurring sugars in it.
Plants draw water up through their roots and distribute it throughout the plant.
While they often may be near the beach, they don’t really grow in salty water, and excess salt is pushed out by the cells in the roots.
They are sweet because the plant absorbs carbon dioxide from the air, and uses sunlight to drive a process called photosynthesis where energy from the light drives a chemical cycle that makes sugar from carbon dioxide and water. If the plant makes more sugar than it uses, the extra is stored either as sugar (which makes the plant sweet) or as a chain of sugar molecules (starch and / or pectin).
