HERE IS YOUR ANSWER :-

_________________________________

The vascular system consists of complex tissues, the phloem and the xylem . the xylem and phloem together constitute vascular bundles.

In dicotyledonous stems , cambium is present between phloem and xylem .such vascular bundle because of the presence of cambium possess the ability to form secondary xylem and phloem tissues , and hence are called open vascular bundles.

In the monocotyledons , the vascular bundles have no cambium present in them. they do not form the secondary tissue they are referred to as closed.

* When xylem and phloem with in a vascular bundle are arranged in the alternate manner on different radii , the arrangement is called radial.
