Following table summarises the differences between a monocot root and a dicot root. Characters Monocot root Dicot root (i) Vascular bundle Polyarch i.e., more than 6 vascular bundles Diarch to hexarch i.e., 2 - 6 vascular bundles (ii) Cambium Absent Present, so secondary growth occurs (iii) Pith Poorly developed Well developed large pith (iv) Activity of pericyde Gives rise to secondary roots and cork cambium Gives rise to lateral roots only Identify the incorrect differences and select the correct option.

In monocot root, a well developed pith is present whereas in dicot root, pith is poorly developed. In monocot root, pericycle gives rise to lateral roots only whereas in dicot root, pericycle gives rise to secondary roots and cork cambium.

	Characters	Monocot root	Dicot root
(i)	Vascular bundle	Polyarch i.e., more than 6 vascular bundles	Diarch to hexarch i.e., 2 - 6 vascular bundles
(ii)	Cambium	Absent	Present, so secondary growth occurs
(iii)	Pith	Poorly developed	Well developed large pith
(iv)	Activity of pericyde	Gives rise to secondary roots and cork cambium	Gives rise to lateral roots only
