The apple is the pomaceous fruit of the apple tree
Species Malus domestica in the rose family Rosaceae. It is one of the most widely cultivated tree fruits. The tree is small and deciduous, reaching 5–12 m tall, with a broad, often densely twiggy crown. The leaves are alternately arranged simple ovals 5–12 cm long and 3–6 cm broad on a 2–5 cm petiole with an acute tip, serrated margin and a slightly downy underside.
Flowers are produced in spring simultaneous with the budding of the leaves. The flowers are white with a pink tinge that gradually fades, five petaled, 2.5–3.5 cm in diameter. The fruit matures in autumn, and is typically 5–9 cm diameter.
The centre of the fruit contains five carpels arranged in a five-point star, each carpel containing one to three seeds.
The tree originated from Asia, where its wild ancestor cultivars vary in their yield and the ultimate size of the tree, even when grown on the same rootstock.
