After peeling a banana almost always there are long and removable fibers(?) on the banana (marked by red arrows). What are they called?
We’re talking about those annoying white strings on bananas, or more technically, “phloem bundles.” (Appetizing name, right?)
If the term “phloem” sounds familiar to you, it’s probably because you were taught about phloem and xylem when you learned about plant biology in middle school science class. Those two terms describe the complex tissues that transport food and water in a plant, providing it with sufficient food, nutrients, minerals and water to grow.
So essentially, these hideous strings distribute nutrients up and down the banana as it grows, allowing us to eat the delicious bananas that we so love.
Therefore, in an informal conversation between friends, etc., I would expect to hear banana strings. On the other hand, if you're writing an academic article or trying to come across as a know-all in an informal conversation, use the term phloem bundles.
