Question

The fruit of watermelon is?
A. Pome
B. Sorosis
C. Pepo
D. Drupe

Answer 1

After pollination and fertilization the fruit develops from a ripe ovary or any floral part and the fruit wall develops from the ovary wall. Fruit wall is known as pericarp & is three-layered epicarp, mesocarp & endocarp. All fruits are classified into three categories based on which type of ovary have they developed. These are simple fruits, aggregate fruits, and composite fruits.

Complete answer:
Option -A- Pome
Pome is simple and succulent false fruit that develops from fleshy thalamus that is edible. Pome is known as false fruit as we are not eating ovary part rather here thalamus is edible. Example - Apple
Option-B-Sorosis
Soros is a composite fruit (entire inflorescence develops into a fruit) that develops from a catkin, spike, and spadix inflorescence as is found in Mulberry, jackfruit, and pineapple.
Option-C-Pepo
Pepo is a type of fleshy fruit developed from a single ovary (simple fruit). Pepo is a simple fruit having hard epicarp which is also known as the rind, fleshy pulp, and numerous flattened seeds. Pepo fruit is commonly found in Cucurbitaceae family Example- watermelon, cucumber, pumpkin etc.
Option-D-Drupe
These fruits (drupe) have characteristic hard and stony endocarp. Drupe is a juicy fruit in which epicarp is thin, the mesocarp is fleshy and the endocarp is stony hard that's why sometimes also referred to as stony fruits. Example - Mango, Coconut
So, the correct answer to this question is an option C "Pepo".

Note: Simple fruits are the ones that develop from the ovary of a single flower. Example - Pome, berries. Aggregate fruits are the one which develops from polycarpillary apocarpous ovary. Many free carpals together form a fruit. Composite fruits are the ones developing from a complete inflorescence. Example: Mulberry, pineapple, jackfruit.
