The fruit of an apple tree it composed of the seed-bearing ovary (core), surrounded by a thick, fleshy hypanthium that is not part of the pericarp. Its derived from the fusion of the bases of the perianth segments (petals and sepals). Some references state that the hypanthium may also contain tissue from the receptacle. In the pome, the thickened, fleshy hypanthium is fused with the ovary wall (seed-bearing core). When you eat an apple, you are primarily biting into the hypanthium tissue. The actual ovary or core is usually not eaten, at least by most humans. Since the fruit contains tissue not derived from the pericarp, it is called an accessory fruit. This is the typical fruit of certain members of the rose family (Rosaceae), including apple, pear, quince and loquat.
