HEY DEAR ...
DICOT ROOT
An inconspicuous pith or may be absent as well.
Mostly the number of xylem bundles are 4–6. So tetra or hexaxylic condition.
Pericycle (a thin parenchymatous circular layer inner to the endodermis) gives rise to lateral roots and secondary meristem (cambium & phellogen).
Cambium appears as a secondary meristem.
Secondary growth is seen cutting the secondary xylem towards the inner side and secondary phloem towards the outer side.
E.g. Root ot wheat.
MONOCOT ROOT
A very well developed parenchymatouscentral pith is present
Xylem shows polyarch condition. Exception= Allium cepa (onion).
Pericycle forms only lateral roots but no secondary meristem.
No cambium is present between xylem and phloem.
E.g. Zea mays
Both dicot and monocot roots have radial & exarch xylem.

The monocot is the plant that has only one cotyledon in the embryo, whereas dicot is the plant that has two cotyledons in the embryo. ... The other big difference between the monocot roots and dicot roots is the presence of some xylem and phloem. In monocot roots, the xylem and phloem are numerous in numbers.
