The ovary wall develops into the pericarp. Seeds dispersed by water are found in light and buoyant fruits, while those dispersed by wind may have specialized wing-like appendages. Remember, insect diversity also matters. This usually involves a buoyant pericarp, as in the fibrous husk of the water-dispersed coconut. Examples of fleshy fruits include apples (Malus) or oranges (Citrus), where the pericarp or some other part of the floral structure becomes swollen with liquid.

Some birds are also known to cache nuts for later. Strawberries are just one fruit that scatters seeds through digestion and defecation, and the maturation process of the fruit includes ensuring that the seeds are ready to germinate. Fruits with velcro-like projections or sticky pericarps latch onto mammal fur or bird feet and are transported to a new locale without needing to survive a journey through the digestive tract (Figure \(\PageIndex{7}\)). The achenes have long hairy appendages that developed from the style of the flower. A diploid megaspore mother cell is produced within the megasporangium, which will divide by meiosis to produce the haploid megagametophyte (see Chapter 7.3.2: Angiosperm Life Cycle for a refresher).
