Radial Vascular Bundle - QS Study
QS Study

Radial vascular bundle: When xylem and Phloem in a vascular bundle lie on different radii alternately from one another, it is called radial vascular bundle. In radial vascular bundles the components are arranged separately. Here the xylem and phloem are arranged separately in different Radii. Radial vascular bundles are typically found in the roots of monocots and dicots.

Radial vascular bundles are found in monocotyledonous roots. These bundles are the characteristic of roots. There is no primary cambium in this bundle and the secondary thickening occurs by the secondary cambium that originates at the time of secondary growth in dicotyledonous root only.
