Usage

What is a tomato? A tomato is a pulpy fruit from the genus Lycopersicon, usually eaten raw or cooked as a vegetable. Culturally, tomatoes are most often enjoyed as a vegetable, but they are botanically classified as a fruit because the tomato is a developed ovary of a seed plant. Scientifically, they are classified as a berry because the tomato develops from a single flower and does not contain a pit. There are several species of tomato. Most are native to Central and South America, with many species being farmed in Mexico. The most common tomato purchased and eaten is the L. lycopersicum, also known as the garden tomato. As it grows, the color of its skin changes from green to dark red and is commonly used for food products like ketchup, tomato sauce, and soups. Other types of tomatoes include cherry tomatoes or Lycopersicon esculentum, named for their small, red appearance similar to a cherry. Currant tomatoes, or Solanum pimpinellifolium, are known for their small size and sweet flavor, while beefsteak tomatoes, or Solanum lycopersicum, grow to be very large and have ridges similar to a pumpkin or gourd. Heirloom tomatoes, which are non-hybrids, come in a variety of sizes and colorsExample: Guinea pigs love cherry tomatoes because they are small and sweet.

Explanation

Although usually called a vegetable and eaten as such, the tomato is actually a fruit that can be eaten raw or cooked. It might be red or yellow in various sizes, and comes in shapes from round to pear-shaped. Since the tomato is native to South America, it makes sense that its name is based in the Spanish tomate, and can be traced to the Aztecs, whose language, Nahuatl, contained the word tomatl, or "the swelling fruit." In 1519, Cortez brought tomato seeds to Spain, where the plant was grown as an ornament but not for eating. The French called them pommes d'amour, or “love apples,” and in 1929 the word became American slang for a pretty girl.
