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
Where companion cells helps in maintaining the pressure gradient in the sieve tubes.
Where plants absorb water through the roots and then give off water vapor through pores in their leaves.
Where activity of cork cambium builds pressure on the remaining layers peripheral to phellogen and ultimately these layers dies and slough off.
