Drupe
A drupe is a fruit in which a fleshy outer region surrounds a hard inner layer, or endocarp, that encloses a seed.
Fruit: In flowering plants, a fruit is the mature ovary, sometimes with associated tissues, that contains or disperses seeds. A drupe is one structural type of fruit.
Peach: The peach is a fruit of Prunus persica, with fuzzy skin, juicy flesh, and a deeply grooved stone. It is a familiar drupe with a conspicuous hard endocarp.
Berry: A botanical berry is a fleshy fruit whose pericarp is largely soft at maturity and usually contains multiple seeds. Unlike a drupe, a berry lacks a hard stone around its seed.
Stone fruit: Stone fruit is a culinary and horticultural grouping of fruits with a hard pit enclosing a seed. This common food category largely corresponds to familiar cultivated drupes.
Pericarp: The pericarp is the fruit wall developed from the ovary wall, often differentiated into distinct layers. Its layers form the drupe’s fleshy exterior and hard inner shell.
Cherry: A cherry is the small, usually red or dark fruit of several Prunus species, with a single hard stone. Its thin flesh surrounds one readily recognized stone.
Pome: A pome is an accessory fruit with a fleshy outer portion and a core containing several seeds. Its seed-bearing core differs from the single stony endocarp typical of drupes.
Prunus: Prunus is a genus of flowering plants that includes cherries, plums, peaches, apricots, and almonds. Many commercially important drupes belong to this genus.
Exocarp: The exocarp is the outermost layer of a fruit’s pericarp. It forms the drupe’s skin, such as the thin skin of a cherry.
Olive: The olive is the oily fruit of Olea europaea, cultivated for food and oil. Its fleshy exterior and single hard pit make it a drupe.
