Question

Cotyledons and testa are respectively edible in
A. Walnut and Tamarind
B. French bean and Coconut
C. Cashew nut and Litchi
D. Groundnut and Pomegranate

Answer 1

Hint: Cotyledons assist a plant embryo get the nutrients it needs to germinate and grow into a photosynthetic organism. They can also be a source of nutritional reserves or help the embryo metabolise nutrition stored elsewhere in the seed. A cotyledon is an important component of the embryo within a plant's seed. The cotyledon may become the embryonic initial leaves of a seedling after germination. A seed's testa is the thick or hard outer covering.

Complete solution:
Let us solve this question by analyzing each of the options.
Option:A – In Walnut the edible part is cotyledon while in Tamarind the edible part is mesocarp.
So, Option:A is not correct.
Option:B – In French beans the edible part is their seeds while endosperm is the edible part in coconut.
So, Option:B is not correct.
Option:C - In Cashew nut the edible part is their cotyledons and fleshy pedicels while in Litchi the edible part is their fleshy aril.
So, Option:C is also not correct.
Option:D – Groundnuts and Pomegranate have edible cotyledons and testa.
So, Option:D is correct.

Hence, option D. Groundnuts and Pomegranate is the correct answer

Note:
Groundnuts are dry, multi seeded lomentum fruits that are split into one seeded segments or mericarps after ripening. Mericarps do not break any farther, and the seeds' cotyledons and testa are edible. Pomegranate fruits are of the balausta kind, with a superior ovary that is multicarpellary, syncarpous, and multilocular. It has a large number of seeds. Endocarp is hard and produces irregular chambers to contain seeds. The testa is fleshy and crimson, whilst the tegmen becomes rigid.
