Question

A small dry, one seeded fruit with pericarp fused with seed coat and forming from monocarpellary gynoecium is
A)Samara
B)Cypsela
C)Siliqua
D)Caryopsis

Answer 1

Exotic fruits are defined as fruits which are not native and that are cultivated outside, available at their place of origin. Many of the exotic fruits are tropical. Fruits are defined as the mature ovary or ovaries of one or more flowers. The mesocarp is usually the fleshy, edible part of the fruit. In most of all the fruits, two, or all three of the layers are fused, and are indistinguishable at maturity.

Complete answer:
Fruits are classified as dry or fleshy. The pericarp develops from a plant's ovary. It forms around the seeds. On fruit, the pericarp is the edible tissue that develops around the seeds. Pericarp is the outermost edible layer of the fruit that develops from the wall of the ovary. It consists of Epicarp, Mesocarp, and Endocarp.

Now let us find solution from given options:
A)Samara: Samara is a kind of dry fruit and also it is indehiscent but it does not have fused pericarp.
B)Cypsela : Cypsela are dry and indehiscent fruit but show the presence of a free pericarp and seed coat.
C)Siliqua : Siliqua is dry but it is a dehiscent fruit and shows presence of a free pericarp and seed coat.
D)Caryopsis : Caryopsis is a kind of dry indehiscent single seeded fruit that show presence of a fused pericarp and seed coat. It is a kind of single seed because it develops from a monocarpellary gynoecium.

Hence, the correct answer is option (D)

Note: Fruits are eaten for obtaining a balanced diet. Different fruits have different edible parts. It depends on the growth they perform. In many fruits’ pericarp is the edible part as in grape. There are usually three layers: endocarp, mesocarp and pericarp.
