Episode Details

Daniel notices the three dark spots on a coconut.

They look like a face. Two eyes and a mouth.

They are not just for looking like a face. Those three spots are germination pores -- soft points in the hard inner shell -- and they reveal something about how the coconut fruit was built.

Usually only one of the three is functional. That is the pore the developing seedling uses to push through when a coconut germinates. The other two are typically sealed. And understanding why there are three at all takes you back to the flower the coconut developed from.

Palm flowers typically have their parts arranged in threes. The coconut's ovary is built from three carpels -- three female reproductive sections. That three-part structure is reflected in the fruit that develops from it. The mature coconut normally contains one seed, but the hard inner shell keeps three pores corresponding to that original three-part construction. Usually only one becomes the functional germination point.

So those three little spots are a map of how the fruit was built -- and a connection back to the flower it came from.

The coconut fruit is also remarkably well equipped for dispersal. The thick fibrous husk helps keep it buoyant. The hard inner shell protects the seed and embryo. The coconut water and meat provide nutrition for the developing seedling. And the germination pore provides a ready-made exit when it is time to grow.

One more thing. The germination pore is the softest part of the shell -- which is why it is also where people pierce a coconut to get the water out. The same place the developing palm uses as its way out is the same place humans use as their way in.

What you will find in this episode:

• What the three spots actually are and what they do
• Why coconuts have three of them -- and why usually only one works
• How the coconut flower explains the coconut shell
• Why the coconut fruit is so well suited for dispersal
• The connection between germination and kitchen technique
• The closing line about what a coconut is carrying

Short, elegant, and the kind of episode that makes every coconut you ever see feel completely different.
