What exactly is "Fruit"?
Typically we think that fruit is just something found in the garden or on our plate, but here is the formal explanation of fruit from Webster's Dictionary:
"A fruit is the reproductive product of a tree or other plant...the edible, succulent product, generally covering and including the seed...or mature ovary. Essentially, fruit is made of two parts: the pericap, or edible flesh, and the seed portion itself."
Note thet from the botanical definition, nuts and seeds fall into the fruit category. Also note that many foods we commonly call "vegetables" are actually recognized by botanists as fruits! These include tomatoes, squash, eggplant, cucumbers, pumpkins, and others.
