How would you distinguish between a monocot stem and a monocot root?

As a rule monocot stem is of a larger diameter than monocot root.
Real difference lies in their anatomy.
Monocot stem shows scattered vascular bundles internally,and no pith. The xylem is endarch( i.e. protoxylem pointing towards the center of the section.
Whereas a root section shows radial vascular bundles , arranged in a circle near the periphery with xylem and phloem alternating with each other and xylem is exarch(i.e. protoxylem facing towards the periphery.
There is a large parenchymatous pith at the center.

Under a microscope, a monocot stem has scattered primary vascular bundles. these vascular bundles even look like inverted faces when focused or enlarged. a monocot root on the other hand, has vascular bundles arranged in an array of ring.
NOTE: the vascular bundles of a monocot root doesn't look like the vascluar bundles of the monocot stem.

The root will have little hairs covering it, while the stem will not.
