A unique feature observed in the dicot root vascular cylinder is the presence of:
Endarch xylem with four protoxylem poles
Exarch xylem with more than six protoxylem poles
Mesarch xylem with two protoxylem poles
Centrarch xylem with a single protoxylem pole

Consider the following statements.
I. In a dicot root, the vascular bundles are collateral and endarch.
II. The innermost layer of cortex in a dicot root is endodermis.
III . In a dicot root, the phloem masses are separated from the xylem by parenchymatous cells that are known as the conjunctive tissue.
