Biology/Banana sections

Question
A banana has how many sections?  (If you push your finger into one end of a banana and push you will receive the answer! I've also tried this with my tongue to make people laugh and be amazed.  No one I know has ever seen this! I couldn't find reference to it on the internet.)

Answer
Dear Glenn,

The fruit of a banana is an accessory fruit (meaning that part of the flower tube contributes to the "finished" fruit) consisting of three carpels arranged around a central axis.  The carpels are the specialized chambers in which the seeds ripen.  (In domestic cultivars, the carpels are parthenocarpic (they develop without seeds), and so won't usually have seeds.)

When you press on a banana, it *should* split into the three sections that are derived from the three carpels.  

Is that what you saw?  :)
