III. The Multiple Fruits (page 6)

 Multiple Fruit Examples

 All of the fruit types we have studied so far arise from a single flower. Multiple fruits, unlike the others, develop from a cluster of flowers. Individual fruits of the multiple cluster develop from one ovary and some accessory parts of the flower. The pineapple is a good example of a multiple fruit. It is cluster of mature ovaries each with accessory parts including the receptacle and portions of the sepals and bracts. The fruit's surface tissue you see in the photograph covers the ovary. This tissue arises from three overlapping sepals and the tip of a bract. Green bracts stick out of the top of the whole pineapple. Flowers were not borne in the axils of these bracts. Seeds are usually absent from commercially grown plants.
