Which of the following statements regarding vascular bundles is INCORRECT?
In roots, xylem and phloem in a vascular bundle are arranged in an alternate manner along the different radii.
Conjoint closed vascular bundles do not possess cambium.
In open vascular bundles, cambium is present in between xylem and phloem.
