Options:

A–embryonal, B–plumule, C–cotyledons, D–epicotyl

A–embryonal, B–epicotyl, C–cotyledons, D–plumule

A–embryonal, B–two, C–epicotyl, D–plumule

A–plumule, B–epicotyl, C–cotyledons, D–embryonal

Correct Answer:

A–embryonal, B–two, C–epicotyl, D–plumule

Explanation:

The correct answer is Option (3): A–embryonal, B–two, C–epicotyl, D–plumule

In a typical dicotyledonous embryo, there are two main parts: the embryonal axis and the cotyledons. The upper part of the embryonal axis, known as the epicotyl, extends beyond the cotyledons and ends with the plumule or stem tip.

The lower cylindrical portion, located below the cotyledons, is called the hypocotyl, which ends at the root tip known as the radicle. The radicle is protected by a root cap.
