Pear

The pears is classified within Maloideae, a subfamily within Rosaceae. Pear is sweet juicy yellow or green fruit with a rounded shape that becomes narrower towards the stalk and grainy in texture. The form of the pear and of the apple respectively, although usually characteristic enough, is not by itself sufficient to distinguish them, for there are pears which cannot by form alone be distinguished from apples, and apples which cannot by superficial appearance be recognized from pears. A major distinction is the occurrence in the tissue of the fruit, or beneath the rind, of clusters of lignified cells known as "grit" in the case of the pear, while in the apple no such formation of woody cells takes place.
