The Stringy Bits on the Side of the Eating Bit of a Banana

Ask the unexpected with Dr. Kathy Mansfield, a senior teaching fellow in the Department of Life Sciences at Imperial College, London. This week's question is from Lisa who asked what are the stringy bits on the side of the edible bit of a banana for? We love your emails, your comments, your stories, your questions. They keep us happy, particularly when you ask something that makes us wonder why we never did and then triggers an urge to find out.
