Fruit or Vegetable

Is tomato a fruit or vegetable?

You are probably going to tell me that tomato is a vegetable.  I would argue that it is actually a fruit.  Why?  Ur...  I don't know.  Seriously! What are fruits? What are vegetables?  I googled it and found out there is no standard answers.  It is summarised as followings:

From The Straight Dope

A fruit is the matured ovary of a flower, containing the seed. After fertilization takes place and the embryo (plantlet) has begun to develop, the surrounding ovule becomes the fruit. Yum. I won’t go on about the four types of fruit–simple, aggregate, multiple and accessory–which explain things like berries and pineapples.  

A vegetable is considered to be edible roots, tubers, stems, leaves, fruits, seeds, flower clusters, and other softer plant parts. In common usage, however, there is no exact distinction between a vegetable and a fruit. The usual example is the tomato, which is a fruit, but is eaten as a vegetable, as are cucumbers, peppers, melons, and squashes. The classification of plants as vegetables is largely determined by custom, culture, and usage.

By the definitions above, the list below are fruits that are often thought to be vegetables:

• Avocado
• Capsicum (green, red, yellow...)
• Cucumber
• Pumpkin
• Squash
• Zucchini
