Alll plants have seeds, yet all seeds are not surrounded by the fleshy accessory tissues we consider "fruits". I'm not botanist, but I'm pretty sure that vegetables would be considered a "fruit", using the term loosely of course. I'm not sure if any "fruit" from trees would be classified as vegetables however.
NO. Anything with a seed is considered a fruit. Things that grow on tree's have seeds. Avocado's are biologically fruits, but in culinary terms they are thought of as vegetables. Also, Olives grow on trees, but they are biologically fruits as well.
Botanically cucumbers are berries too. Culinary considerations are different.
There are trees with leaves that could be used as spices or for tea, but I don't know if I'd call those vegetables.
okay...you said anything with a seed is a fruit...cucumbers have seeds...they are vegetables...
no they can not;but a fruit can veg. grow from the ground.
