Answer 2

A branch is a part of a tree which grows out from the trunk or from a bough.

The thorn is a modified, sharp-pointed stem.

It occurs in the axil of a leaf where a branch would normally develop.

The spine is technically a modified, sharp-pointed leaf.

Since it has a bud in its axil, the spine occurs in the relative position of a leaf.
