Short Note

Answer the following question.

A section of the stem had vascular bundles, where one tissue was wrapped around the other. How will you technically describe it?

Concentric vascular bundle:

When one vascular tissue is completely encircling the other, it is called a concentric vascular bundle.
When phloem is encircled by xylem, it is called a leptocentric vascular bundle, whereas when xylem is encircled by phloem, it is called a hadrocentric vascular bundle.
When xylem is encircled by phloem on both faces, it is called as amphicribral vascular bundle. When phloem is encircled by xylem on both faces it is called an amphivasal vascular bundle.
