Question

The portion of embryonal axis between plumule(future shoot) and cotyledons is called.

• A. Hypocotyl
• B. Epicotyl
• C. Coleorhiza
• D. Coleoptile

Answer 1

The correct option is B Epicotyl

Each seed has an outer covering called seed coat. The seed coat encloses an embryo which is differentiated into plumule, radicle and cotyledons. Plumule is the upper terminal part of embryo which elongates and develops into the future shoot. The lower end of embryo is radicle, which develops into future root. In a seed, one (in monocots) or two (in dicots) cotyledons may be present. The part of embryonic axis between the plumule and point of attachment of cotyledons is called epicotyl.

So, the correct option is 'epicotyl'.
