Question

Assertion: In a dicotyledonous embryo, the portion of embryonal axis above the level of cotyledons is the epicotyl and the portion below the level of cotyledons is hypocotyl.

Reason: The epicotyl terminates with radicle or root tip and hypocotyl terminates with plumule or shoot tip.

• A. Both assertion and reason are true and reason is the correct explanation of assertion.
• B. Both assertion and reason are true but reason is not the correct explanation of assertion.
• C. The assertion is true but reason is false.
• D. Both assertion and reason are false.

Answer 1

The correct option is C The assertion is true but reason is false.

A dicotyledonous embryo consists of an embryonal axis and two cotyledons.
Epicotyl is the portion of embryonal axis above the level of cotyledons. Epicotyl terminates with the plumule or stem tip.

Hypocotyl is the cylindrical portion of the embryonal axis below the level of the cotyledons. Hypocotyl terminates at its lower end in the radicle or root tip.

Hence, assertion is true and reason is false.
