False Fruits

Did you eat your daily allowance of fruit today? What is fruit? Sure, you knew tomatoes oddly are, but what else? Apparently, not much.

Strawberries, you will be glad to know, are a 'false fruit'. Which seems reasonable enough. But at this point a small doubt started to grow in my mind... what, actually, then, was a real fruit? Oranges? No, they're a modified berry. Bananas? Leathery berry. Plums? Drupe -- fleshy bit with one stone inside.
