1. It’s a berry.
A strawberry isn’t, a raspberry isn’t, but a banana is a berry, botanically speaking. So are tomatoes, grapes and eggplants. A berry is the fruit produced by the ovary of a single flower, except for stone fruits. You can tell that raspberries aren’t berries by their multiple little round sacs of deliciousness, and strawberries because they have no seeds inside. Other things, it’s best to look it up.
