In the lаnguаge оf bоtаnists (scientists whо study plants), fruit has a different meaning than in everyday talk about food. To most of us, fruit refers to sweet or tart foods like apples, peaches, and lemons. To botanists, however, fruit also includes seed-containing "vegetables" such as cucumbers, eggplant, olives, peas, squash, string beans, and tomatoes (which are berries). Botanically speaking, cashews and other nuts are single-seed fruits. Many plants that we don't eat-for example, milkweeds and azaleas-also are fruits. So, a mix of milkweeds and azaleas is a fruit cup; a package of dried fruit and nuts is a package of fruit and more fruit; and parents who scold, "Eat your vegetables!" when their children refuse to eat string beans or peas could, instead, coax, "Don't you want to eat your fruit?"
