The botanical definition of a berry is a fleshy fruit produced from a single flower and containing one ovary. Grapes and bananas are two common examples. The berry is the most common type of fleshy fruit in which the entire ovary wall ripens into an edible pericarp. They may have one or more carpels. The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, that have air rather than pulp around their seeds.
Prunus avium, commonly called wild cherry, sweet cherry, bird cherry, or gean, is a species of cherry native to Europe, western Turkey, northwestern Africa, and western Asia, from the British Isles south to Morocco and Tunisia, north to the Trondheimsfjord region in Norway and east to the Caucasus and northern Iran, with a small disjunct population in the western Himalaya. This species, in the rose family (Rosaceae), has a diploid set of sixteen chromosomes (2n=16). All parts of the plant except for the ripe fruit are slightly toxic, containing cyanogenic glycosides.
