Question

Which one of the following does not have polycarpellary ovary?
A. Guava
B. Apple
C. Coconut
D. Fig

Answer 1

Hint:- The polycarpellary ovary is defined as the condition in which a plant consists of, or originated from 2 or more united or separate carpels or ovaries. Polycarpellary ovaries can not be unilocular (ovary which consists of single locule) or multilocular (ovaries which consist of a large number of locules).

Complete Answer:-
Guava is a false berry because it originates from an inferior polycarpellary ovary. The epicarp of the guava constitutes the crust, the mesocarp is the fleshy part and the endocarp persists thin or membranous. Apple is developing from a polycarpellary ovary. It is a kind of pome because in this thalamus is fleshy, swollen, and surrounds the fruit. Hence forms the edible part of the fruit. The pericarp is thin and papery.
Coconut is a kind of drupe which formed from either a carpellary or a tricarpellary ovary. The pericarp is composed of 3 layers. The epicarp forms the skin of the fruit, the mesocarp is fleshy or fibrous and the endocarp is tough and Stoney. Fig is a kind of syconus i.e. composite fruit which produces from a monocarpellary ovary which constitutes the fruitlets. The actual fruit is developed from several fruitlets in hypanthodium inflorescence. Fleshy receptacles form the edible part.
Thus, the right option is D.

Note:- The study of fruit and fruit-bearing plants is known as pomology. The water of coconut is known as degenerated liquid endosperm. Parthenocarpy is defined as the artificial process of formation of fruits without fertilization and fruit produced by this process either lacks seed or has no viable seeds. For example, banana, fig, kiwi, etc.
