The vegetable often mistaken for a fruit due to its seeds is the tomato. Botanically, tomatoes are classified as fruits because they develop from the ovary of a flower and contain seeds. However, in culinary contexts, they are typically treated as vegetables due to their savory flavor and common use in salads, sauces, and various dishes. Tomatoes come in many varieties, including cherry, heirloom, and beefsteak, and are rich in vitamins, particularly vitamin C, and antioxidants like lycopene. This confusion between fruits and vegetables is common in cooking and gardening.
