Question

Cotyledonary node of embryo lies between

• A. Hypocotyl and radicle
• B. Epicotyl and plumule
• C. Epicotyl and hypocotyl
• D. Cotyledons and radicle

Answer 1

The correct option is C Epicotyl and hypocotyl

Cotyledonary node of embryo lies between epicotyl and hypocotyl. The epicotyl is the embryonic shoot above the cotyledons. In most plants the epicotyl will eventually develop into the leaves of the plant. In dicots, the hypocotyl is what appears to be the base stem under the spent withered cotyledons and the shoot just above that is the epicotyl.
In monocot plants, the first shoot that emerges from the ground or from the seed is the epicotyl, from which the first shoots and leaves emerge.
Therefore, the correct answer is option C.
