Why do Bananas Have a Curve?

As many of you know, the banana is my favorite fruit. An apple banana* a day keeps the doctor away!

Bananas start off by being very short and straight:

As time goes on, however, they begin to curve upwards...

Due to a process known as negative geotropism, which means that the bananas grow away from the force of gravity!

They do this because in the forests, if they started to grow sideways towards the light that penetrates through the trees and plants above them, they would topple over. So bananas figured out that if they grew up towards the light instead of sideways, their plant would not topple over, and they would all be safe.

Thank you for existing, bananas.
