For most people, the distinction between vegetables and fruits is fairly clearly. Scientists, however, have varied opinions in this regard. For example, horticulturists categorise a watermelon as a vegetable despite its general acceptance as a fruit. Botanists identify a tomato as a fruit even though it is commonly used as a vegetables.
These differences stem from the ways in which fruits and vegetables are classified. For a botanist, a fruit is a seed – bearing portion of flowering plant or tree. According to this definition, a tomato is a fruit. For a horticulturist, a vegetable is the edible portion of a plant that must be replanted annually. According to this view, a tomato is a vegetable. A horticulturist sees a fruit as coming from a plat or tree that lives at least two years. In the case of fruits and vegetables that meet the criteria of both groupd of scientists, such as apples or potatoes, there is no conflict.
