You probably think you know what a fruit is.
Apples. Oranges. Grapes. Things you put in a fruit bowl and occasionally forget about until they start developing their own civilization.
But botanists have a much broader definition.
A fruit develops from a flower's ovary, the part that contains the ovules. After fertilization, those ovules typically become seeds, and the surrounding ovary develops into a fruit.
And that means quite a few things you've been calling vegetables are actually fruits.
Tomatoes? Fruits.
Cucumbers? Fruits.
Bell peppers? Fruits.
Pumpkins? Also fruits.
And fruits don't even have to be fleshy.
An acorn is a type of dry fruit called a nut. The little winged helicopter things that fall from maple trees are fruits called samaras.
The job of a fruit isn't necessarily to taste delicious. It's to protect seeds and often help them spread.
Some fruits tempt animals into eating them. Others hitch rides on the wind, float in water, or simply drop to the ground.
So when a botanist says fruit, they're talking about plant reproduction, not what belongs in a smoothie.
And technically, a tomato is a fruit.
But if you put one in my fruit salad, we're having words.
