Are squash fruit? If not, why not? Seeds on the inside, what?

But in that case, roses are fruit.

This. Must. Stop.

No! Roses are red! The potential for confusion is endless...

Rose hips are also red, and have seeds on the inside.

I have no idea. I classify them as weird.

Aren't rose hips fruit?

Squash are definitely fruit. I think they may be technically berries, unless I'm talking out of my ass here.

It's basically a grocer's term. It's not a technical term.

ETA: fruit is, that is.

Raspberries are technically drupes.

Me so wrong:

Fruit: Can be defined as simply as the seed-bearing part of the plant. It is more commonly used as a term to describe a mature ovary containing the seeds of the plant. Botanically, "fruit" is a much broader term than what it tends to define in common language. The pod of a pea (the legume) is a fruit, as is the samara (a winged seed-bearing structure) of an ash tree. Most of what we call fruits are really berries, drupes or pomes. Fruits may be "simple", where they develop from one carpel or several fused carpels (examples would be blueberry or grape); "aggregate", where each carpel from a single flower develops into a separate part of the overall fruit (examples would be raspberry or strawberry); and "multiple", where all the carpels of more than one flower on a plant produce a single fruit (an example would be pineapple).

Berry: A fleshy fruit comprised of one to several carpels, each of which usually has many seeds. The inner layer of the fruit coat, surrounding the seeds, is fleshy. (Examples would be tomato, blueberry or grape.)

Drupe: A fleshy fruit comprised of one to several carpels, each of which usually has a single, large seed. The inner coat of the fruit is woody or stony and fixed tightly to the seed. (Examples would be plum or cherry; fruits with a "pit".)

Pome: A fleshy fruit where the fleshy part is derived from the perianth, the structure that normally surrounds the base of a flower. This is a specialized type of fruit that only some members of the rose family produce. (Examples would be apple and hawthorn.)

Kewl. I told somebody a pumpkin was a fruit the other day, and although he'll never check, I like to think there's some technical sense in which I'm correct. Seed bearing part of the plant. Mature, seed-containing ovary. Check.
