Question

Pick u the wrong differences between dicot and monocot root.

	Character	Dicot Root	Monocot Root
(a)	Activity of pericycle	Lateral root production	Secondary growth and cambium
(b)	Vascular bundle	Diarch to tetrarch	Polyarch
(c)	Cambium	Lateral, developed	Absent
(d)	Pith	Well developed	Poorly developed

• A. b, d
• B. a, c
• C. a, d
• D. a, b

Answer 1

The correct option is C a, d

a) Wrong – because in dicot root pericycle is meant for production of lateral roots and cambium whereas in monocot root it is pericycle is meant for lateral production only.

b) True – In dicot root stele is diarch to tetrarch, whereas in monocot root, stele is polyarchy.

c) True – In dicot root, cambium is developed laterally, whereas in monocot root, cambium is absent.

d) False – because, in dicot root is pith is poorly developed, whereas in monocot root pith is well developed.

So, the correct option is ‘a,d’.
