fruits
Fruits may be classified as simple, aggregate, multiple, or accessory, depending on their origin Figure 32.22 . If the fruit develops from a single carpel or fused carpels of a single ovary, it is known as a simple fruit, as seen in nuts and beans. An aggregate fruit is one that develops from more than one carpel, but all are in the same flower: the mature carpels fuse together to form the entire fruit, as seen in the raspberry. Multiple fruit develops from an inflorescence or a cluster of flowers. An example is the pineapple, where the flowers fuse together to form the fruit. Accessory fruits sometimes called false fruits are not derived from the ovary, but from another part of the flower, such as the receptacle strawberry or the hypanthium apples and pears .
