Question

Edible part in ‘Sorosis’, a composite fruit, is
A. Cotyledons
B. Endosperm
C. Perianth and peduncle
D. Fleshy thalamus

Answer 1

Hint: Composite fruits develops from the whole inflorescence and in Sorosis (another name of jack fruit) the fruit develops from the spadix inflorescence (in this type the peduncle is thick, long as well as fleshy).

Complete Answer:
- In the given question we need to find which of the options is an edible part in Sorosis or jackfruit.
- So, the idea of cotyledons is very clear to us that they are the embryonic leaf present in the seed bearing plants they become the first leaves of the seedlings.
- When it comes to endosperm it is a tissue which provides nutrition in the form of starch making it a wrong option.
- As we know that perianth and peduncle both combine to form the inflorescence as perianth comprises petals and sepals whereas the peduncle comprises the stalk on which the flower is present. Making it a whole inflorescence that develops into fruit.
- We also know that fleshy thalamus is the edible part of a false fruit so this also gets eliminated from the options.

So, the correct option is C as they are the only structures that form the whole of the inflorescence.

Note: In the case of composite fruits all the structures get developed from the inflorescence only. Sycosis (Ficus) is one of such examples of composite fruits.
