Question

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 pericycle	Gives rise to secondary roots and cork cambium	Gives rise to lateral roots only

Identify the incorrect differences and select the correct option.

• A. (i) and (iii)
• B. (i) and (iv)
• C. (iii) and (iv)
• D. (ii) and (iii)

Answer 1

Answer: (C)

(iii) and (iv)

On comparing monocot and dicot roots -

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 given rise to secondary roots and cork cambium.

So, the correct answer is (C).
