Question

1. The region of the axis between the
point of attachment of cotyledons
and the plumule.
Epicotyl
Radicle
Hypocotyl
Tegmen​

Answer 1

Answer:

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'.
