The irony is that only one of those (carrot) is actually a vegetable... quick rule of thumb (beyond asking yourself "is this the fruiting body of a plant (the reason why mushrooms are closer to being a fruit than a veggie, though it is neither) is, if you are eating the whole of a plant, its a veggie, if its just the good part you pluck off, a fruit.
but why all the segregation of plants? can't we all agree that there are some really yummy ones out there?
