Have you ever looked at the way a specific food grows and been totally surprised? We’ve certainly felt that way – especially about asparagus and pineapples. Now the banana curve is blowing our minds (with how little we know about our food).
How the banana gets its curve
The reason bananas don’t grow straight and instead have a curve is so that they can retrieve sunlight. It makes sense, we just couldn’t quite picture it at first.
According to Chiquita, “Bananas go through a process called ‘negative geotropism’…What it means is that bananas grow away from the ground, instead of growing towards it, hence the ‘negative’ geotropism.”
Despite bananas being ubiquitous on grocery store shelves, they come from the rainforest (or at least places that can simulate that environment). In a place with so much foliage, bananas had to find a way to claim some sunlight for themselves since they hang downward.
Bananas evolved not to grow straight up but rather to curve in order to get around the foliage and soak up some rays.
More about banana growth
You might think that if it’s looking for the sun, a banana would evolve to grow upwards. But they’re simply too heavy to do that. Because gravity pulls them down, they develop a slight curve rather than a new growth pattern.
Not only is banana growth a fun new fact for us, but we also didn’t know they were considered a berry. Bananas may have actually been one of the first fruits. They date back about 10,000 years, although they taste much different now.
And it turns out the world loves them – we consume about 100 billion bananas globally every year. — WTF fun facts
