Question

Caruncle of albuminous dicot seed is derived from _________.

• A. Cotyledon
• B. Embryo
• C. Integument
• D. Peduncle

Answer 1

The correct option is C Integument

A. Cotyledon is a part of embryo present within the seed.

B. Embryo is a part of seed that has precursors for roots, stem and leaves.

C. Integument is the outermost multicellular covering of an ovule.

D. Peduncle is the stalk of inflorescence (flowers and fruits).

Caruncle is a fleshy, whitish structure present on micropylar end of seed, which arises due to the proliferation of cells at the tip of outer integument on the side of funiculus or all round the micropyle. Hence, caruncle is derived from integument.

So, the correct answer is 'Integument'.
