Why does the seed of the coconut tree have a liquid in it?

Question

What is the purpose of water in the coconut seed? The reason I ask this is that I was reading about coconut water and all the benefits it has for us Humans. But why does the tree put a liquid in the seed? I read a lot more and learned that the liquid becomes a solid and is called endosperm, which is food for the coconut tree. I'm still not happy with that answer because all seeds are food for the plant they become. They are also a lot more. I have come up with a very good explanation for the existence of coconut water and I want see if anyone else has any ideas. Remember, I am not trying to find out why there is food in the shell. That's obvious.

Answer 1

Every plant is unique; so are their fruits and seeds. The endosperm of the coconut fruit is very aqueous and unlike that of the bean or pea is not completely absorbed at maturity. In the early stages of development the endosperm of the coconut fruit is suspended in the water. As it matures, it is deposited into the pulp and the water is left behind in the hollow center.
