A Strawberry is Not an Actual Berry, but a Banana is
Strawberries and raspberries aren't really berries in the botanical sense. They are derived from a single flower with more than one ovary, making them an aggregate fruit. True berries are simple fruits stemming from one flower with one ovary and typically have several seeds. Tomatoes fall into this group, as do pomegranates, kiwis and—believe it or not—bananas. (Their seeds are so tiny it's easy to forget they're there.)
