While a cherry has the appearance of a berry, it is not actually classified as one. Berries are fruits that have fleshy pericarps, one or more seeds and are completely edible. Cherries are fleshy, but because of the pit in the center, are not completely edible.
Cherries are actually classified as drupes, which include fruits that have one seed surrounded by a hard shell. Other examples of drupes include peaches, nectarines and plums. Common examples of berries include cranberries and blueberries. Lesser known examples of berries include grapes, tomatoes, papaya, guava, bananas and avocados. Additionally, some common fruits that are called berries, such as raspberries and blackberries, are technically not berries at all and fall into the drupe category.
