Wikipedia: List of common misconceptions
“The tomato is now mostly accepted as a fruit but many other vegetables are also fruits. For example peppers and cucumbers are also fruits since they contain seeds. In fact, pea pods are fruits as well, while peas are seeds. There isn’t any scientific classification for “vegetable”. Any vegetables that we eat are just parts of a plant; like roots (potatoes and carrots), stems (celery and rhubarb), leaves (lettuce and spinach) and flowers (broccoli and cauliflower).” Everything you know is wrong!
