Fruit anatomy Fruit anatomy Fruit anatomy is the plant anatomy of the internal structure of fruit. Fruits are the mature ovary or ovaries of one or more flowers. In fleshy fruits, the outer layer (which is often edible) is the "pericarp", which is the tissue that develops from the ovary wall of the flower and surrounds the seeds. But in some seemingly pericarp fruits, the edible portion is not derived from the ovary. For example, in the fruit of the ackee tree the edible portion is an aril, and in the pineapple several tissues from the flower and stem are involved. The
Aggregate fruit make a larger fruit. Aggregate fruits may also be accessory fruits, in which parts of the flower other than the ovary become fleshy and form part of the fruit. The individual parts of an aggregate fruit come in many forms. Common examples are: The components of other aggregate fruit are more difficult to define. For example, sugar apple ("Annona" spp.) fruit are made up of individual berry-like pistils fused with the receptacle. Aggregate fruit An aggregate fruit or etaerio () is a fruit that develops from the merger of several ovaries that were separate in a single flower. In contrast,
