papaya(pəpī`ə), soft-stemmed tree (Carica papaya) of tropical America resembling a palm with a crown of palmately lobed leaves. It is cultivated for its melonlike yellow fruits eaten raw or cooked and, more recently, for the juice which has become a commercial item. The juice contains the enzyme papain, somewhat similar to pepsin and digestant in action; the enzyme is used in commercial meat tenderizers. The papaya is also called melon tree and pawpaw. In the Caribbean area the fruit is called fruta bomba. Several other Andean species, as well as the genus Jacartia, also have edible fruits. The papaya is classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

(Carica papaya), a fruit tree of the family Papayaceae (Caricaceae). Five to seven large fingerlike leaves on long stems are attached in bunches at the top of a short (4-8 m) branchless trunk. The dioecious blossoms are yellowish white. The stamens are in the racemes, and the pistils, which grow singly, are in the axil. The flowers are either diclinous or hermaphroditic. Although the papaya grows rapidly without special soils, its life span is short and it cannot survive frost. The papaya is cultivated in the tropics; a wild counterpart is not known. Its fruit, which resembles a melon, is used for food, and its milky juice is used to make the enzyme papain.
