There are often heated debates whether various produce is considered a fruit or vegetable (take the eggplant or aubergine for instance).
However, I've always considered strawberries to be a fruit. My parents used to grow strawberries in their backyard and I remember the onset of summer where the plants would produce small white flowers which in turn matured to become succulently sweet, red strawberries.
The question arises if it starts it's lifecycle as a flower then shouldn't it be classed as a flower and not a fruit.
I go with the analogy that a butterfly is the by product and mature status of a pupae and so strawberries are the edible fruit from the flowers. One makes the other but is not necessarily the same thing.
