Question

The chief edible part in (a) groundnut (b) jackfruit (c) apple and (d) mango fruits are
A. (a) Endosperm, (b) Inflorescence axis, (c) Mesocarp, (d) Endocarp
B. (a) Cotyledons, (b) Succulent perianth, (c) Fleshy thalamus, (d) Mesocarp
C. (a) Cotyledons, (b) Endosperm, (c) Mesocarp, (d) Fleshy Thalamus
D. (a) Cotyledons, (b) Fleshy thalamus, (c) pericarp, (d) Mesocarp.

Answer 1

Hint: In fruits the external edible part is the pericarp which is produced from the ovary and enclosing the seeds, but in a few species other tissues help to form the edible portion. The pericarp consists of three parts from exterior to interior, they are- epicarp, mesocarp and endocarp.

Complete answer:
To answer this question, first, we need to know about fruits and its edible parts. Fruits are the fully developed ovary one or multiple flowers. In fleshy fruits, the external part is the pericarp, which is the tissue that is produced from the wall of ovary of the flower and encloses the seed to save it in environments apart from the parent plant. Apple is a type of pome fruit in which a simple, fleshy but false fruit as it is surrounded by a fleshy thalamus which is edible while actual fruit lies within. The fleshy thalamus is the edible part of an apple.
Now, let us find the solution from the option.
>Edible part of groundnut (Arachis hypogea) is the cotyledons of the seed.
>In jackfruit (Artocarpus heterophyllus) the edible part is the succulent perianth.
>The edible part of the apple is the fleshy thalamus, while that in mango is the mesocarp.

Thus, the correct option is B. i.e. (a) Cotyledons, (b) Succulent perianth, (c) Fleshy thalamus, (d) Mesocarp.

Note:In some fruits, the edible portion is not derived from the ovary, but rather from the aril, such as the mangosteen or pomegranate, and the pineapple from which tissues of the flower and stem provide food. Fruits are found in three main anatomical categories: aggregate fruits, multiple fruits, and simple fruits.
