Detailed explanation-1: -So the correct option is ‘Angiosperms and dicot’
Detailed explanation-2: -Vascular tissues. Most dicot (eudicot) roots differ from eudicot stems in having a lobed column of primary xylem as their core with phloem tissue occurring as strings of cells between the lobes. This arrangement is called a protostele.
Detailed explanation-3: -The Dicot root contains radial vascular bundles.
Detailed explanation-4: -Assertion :In the dicot root, the vascular cambium is secondary in origin. Reason: Secondary growth occurs in stems and roots of gymnosperms also.
Detailed explanation-5: -Pericycle gives rise to cork cambium and lateral branches. Between xylem and phloem elements, parenchyma cells are present constituting conjunctive tissue, which later becomes a secondary meristem. Hence, both of these are responsible for the development of vascular cambium.
