Banana fun fact: Bananas ripen faster when you put them in a bag with other fruit like apples or tomatoes. That is because these fruits produce chemical substances while ripening that induces a faster ripening process in the bananas.
Funfact: The original banana fruits were small, green and full of seeds. The modern type of banana (The “Cavendish”) has only tiny seeds, is sterile and has to be reproduced asexually. Thus most bananas around the world are nowadys identical clones of each other.
