Answer 1

Answer:

The cylindrical portion below the level of cotyledons on embryonal axis is

(1)Epicotyl ✔✔✔

(2)Hypocotyl

(3)Radicle

(4)Plumule

Answer 2

Answer:

The cylindrical portion below the level of cotyledons on embryonal axis is Hypocotyl.

Explanation:

1. Epicotyl:

• It is a portion above the level of cotyledons on the embryonal axis.

• It is composed of shoot apex and leaf primordia.

2. Hypocotyl:

• It is a portion below the level of cotyledons on the embryonal axis.

• It is a transition zone between the shoot, the root and the radicle.

3. Radicle:

• It is a part of the roots and is below the level of hypocotyl.

• It develops into primary roots and part of the embryo.

4. Plumule:

• It is a primitive shoot or stem of an embryo.

• It provides food to the growing plants.

So, from the above discussion, it is proved that the hypocotyl is the cylindrical portion below the level of cotyledons on the embryonal axis.
