Pith - Large and well developed in monocotyledonous root.
Root hairs - Helps in preventing water loss due to transpiration
Sieve tube elements - Its functions are controlled by the nucleus of companion cells.
Stomatal apparatus - Consists of stomatal aperture, guard cells and surrounding subsidiary cells
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.

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.
