Answer 2

Answer:

Hope this answer helps you!

Explanation:

Node: The leaves arise in the regions of the plant known as the plant nodes and are therefore the point of attachment of the leaves.

The region of the plant between two nodes is known as the internode.

The angle between the upper surface of the leaf and the stem from which it arises is known as the axil.

The petiole is the stalk which attaches the leaf to the stem.

So, the correct answer is 'Node'.
