Are fruits and vegetables different just because of the seeds

You have it exactly right

The story goes that tomatoes (fruit) were declared a veggie to please the Hunt family, who were giant campaign contributors, and who wanted ketchup to be counted as a vegetable on school lunch menus so they could get richer. Other fruit- veggie mixups were from a lack of information or of taste. Best wishes 😇

Fruits have interior seeds. Tomatoes, pumpkins, and cucumbers are technically fruit but we use them as vegetables.

I don't really know, but watermelon is a vegetable, just learned that. Good Luck!

Vegetables have stems (celery), roots (carrots) and leaves (lettuce). Fruits grow on vines (grapes, cucumbers), trees ( peaches, cherries) and stalks (tomatoes, corn).
