The ovary, which surrounds the developing seed, becomes the fruit. Simple fruits are derived from an individual ovary and may be fleshy, as in a peach or plum, or dry, as in a pea pod or a sunflower husk. Some ovaries are compound, consisting of several sections. This is apparent in fruits such as apples and tomatoes. There are also compound fruits, which develop from several individual ovaries. Blackberries and raspberries are examples of fruits in this group.
