Question

Which of the following fruit develops from hypanthodium inflorescence?

• A. Sorosis
• B. Syconus
• C. Siliqua
• D. Follicle

Answer 1

Answer: (B)

Syconus

Sorosis is a composite fruit develop from a female spike, e.g., pineapple.

Syconus is a fruit developed from hypanthodium inflorescence. A syconium is the hypanthodium inflorescence borne by figs formed by an enlarged, fleshy and hollow receptacle with multiple ovaries on the inside surface. In essence, it is really a fleshy stem with a number of flowers, so it is considered both a multiple and accessory fruit. Here, the receptacle is fleshy and forms hollow ball like structure with an apical opening. Three types of flowers develop on the inner surface of the receptacle. The female flowers are towards the base, male flowers are towards the orifice and short styled sterile female flowers are in between.
Siliqua is a long, cylindrical fruit formed from bicarpellary, syncarpous pistil with ovary having two parietal palcenta, e.g., radish.

Follicle is a single ripened ovary that splits open along one seam. It may occur singly or in clusters.
Thus, the correct answer is option B.
