Strawberries -

Strawberries are not berries (and, shockingly, neither are blueberries, raspberries, or blackberries). True berries are produced through a single ovary. Instead, strawberries and the like are actually called accessory fruits. What about real berries? Well, a few examples include grapes, pumpkins, and...bananas.
