Question

Choose the incorrect pairs from the following. \[ \begin{aligned} \text{I. Pine apple} &- \text{Syconus} - \text{Juicy succulent bracts} \\ \text{II. Jack fruit} &- \text{Sorosis} - \text{Succulent perianth} \\ \text{III. Fig} &- \text{Syconus} - \text{Fleshy peduncle} \\ \text{IV. Cashew} &- \text{Nut} - \text{Cotyledons and succulent bracts} \end{aligned} \]

• A. I and II
• B. II and III
• C. I and IV
• D. III and IV

Hint:

Pineapple and Jackfruit $\rightarrow$ Sorosis Fig $\rightarrow$ Syconus Cashew apple $\rightarrow$ swollen pedicel

Answer 1

The Correct Option is C

Concept: Multiple fruits develop from an entire inflorescence. The important examples include Sorosis and Syconus. Knowledge of the edible portions of fruits is essential for identifying correct botanical classifications.

Step 1: Examine Pair I.
Pineapple develops from a spike-like inflorescence and forms a multiple fruit known as: \[ \boxed{\text{Sorosis}} \] The given pair mentions Syconus. Therefore Pair I is incorrect.

Step 2: Examine Pair II.
Jackfruit is a classic example of: \[ \boxed{\text{Sorosis}} \] The edible part includes succulent perianth and axis. Thus Pair II is correct.

Step 3: Examine Pair III.
Fig develops into: \[ \boxed{\text{Syconus}} \] The fleshy receptacle (hypanthodium) forms the edible portion. Thus Pair III is correct.

Step 4: Examine Pair IV.
Cashew fruit consists of: \[ \text{True fruit (nut)} + \text{swollen pedicel (cashew apple)} \] The edible part is not formed by succulent bracts. Hence Pair IV is incorrect. Therefore the incorrect pairs are: \[ \boxed{\text{I and IV}} \] Hence option (C) is correct.
