In dicots vascular bundles are arranged in a ring.
Dicots have cambium for secondary growth.
In dicots vessels with elements are arranged end to end.
Cork cambium is present in dicots
Lenticels occur in most woody trees.
Sclerenchymatous cells are usually present in cortex.
The vascular tissue system is divided into three main zones- cortex, pericycle and pith.
The conjoint vascular bundles usually have the xylem located only on the outer side of the phloem.
