What Is a Fruit?

- Ellie Mendelson, Cecilia Zumajo-Cardona, & Barbara Ambrose

Fleshy fruits have high water content in the pericarp, and a fleshy mesocarp once they are mature. This means that fleshy fruits are juicier than dry fruits. The group of fleshy fruits includes many of the fruits that you may find in the grocery store, and many sweet fruits, such as peaches and apples. Pomegranates, although we eat the seed and not the fruit, also fall under this category, because their pericarp is soft and fleshy. Avocados, peaches, plums, and other fruits with pits are also fleshy fruits, because they have a thick and fleshy mesocarp. Peppers, cucumbers, and tomatoes are also examples of fleshy fruits, even though they are usually referred to as vegetables. In fact, most edible fruits fall into the category of fleshy fruits. These fruits use animals, such as birds or humans, to disperse the seeds.
Dry fruits are hard and dry when they are fully mature. The pericarp of dry fruits still has three layers—exocarp, mesocarp, and endocarp—but compared with fleshy fruits, they are thinner and do not have as much water.
