Vegetables and fruits are sometimes loosely distinguished by the usual need of cooking the former for the use of man, while the latter may be eaten raw; but the distinction often fails, as in the case of quinces, barberries, and other fruits, and lettuce, celery, and other vegetables. Tomatoes if cooked are vegetables, if eaten raw are fruits.
