Is the tomato a fruit or vegetable

[Shlup]

The main part of a plant is a vegetable, the things that grow off of plants are fruits. Things that grow off of trees, bushes, and vines are fruit. Carrots and potatoes are vegetables because the plant grows off of them, rather than the other way around.

Flower are fruit? What about lettuce and cabbage? Nuts? The fig? Peas?

Well there are other criteria too, fatty.
