Question

Drupe contains :

• A. Stony endocarp
• B. Stony mesocarp
• C. Edible mesocarp
• D. Both (A) and (C)

Answer 1

The correct option is D Both (A) and (C)

Drupe is a fruit like mango and coconut. In this outer fleshy part (exo-carp or skin or mesocarp or flesh) surrounds a shell of hardened endocarp with seed inside.

Drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp or skin and mesocarp or flesh) surrounds a shell (the pit, stone or pyrene) of hardened endocarp (stony endocarp) with a seed (kernel) inside.

These fruits usually develop from a single carpel and mostly from flowers with superior ovaries (polypyrenous drupes are exceptions).

The definitive characteristic of a drupe is that the hard, lignified stone is derived from the ovary wall of the flower. In an aggregate fruit composed of small, individual drupes, each individual is termed as a drupelet.

So, drupe contains stony endocarp and edible mesocarp.
