Tomatoes are both a fruit and a vegetable, depending on the context in which they are being referred to. Botanically, tomatoes are fruits because they contain seeds and grow from the flower of the tomato plant. However, in culinary uses, tomatoes are considered vegetables. The term "fruit" is used to describe sweet and fleshy botanical fruits, while "vegetable" is used to indicate a wide variety of plant parts that are not so high in fructose. In common usage, a fruit is a plant part that is used chiefly in desserts, while a vegetable is defined as a plant part eaten with the principal part of the meal. Therefore, roots, tubers, stems, flower buds, leaves, and certain botanical fruits, including green beans, pumpkins, and tomatoes, are all considered vegetables by nutritionists. In summary, tomatoes are botanically fruits but are usually prepared in savory dishes, which is why they are considered vegetables in culinary uses.
