Which of the following organs may undergo secondary growth?

i.Only stems

ii.Only roots

iii.Only leaves

iv.Stems and roots

v.Leaves and stems

vi.All of the above

vii.None of the above

Solution

A) ONLY LEAVES

Axillary bud (or lateral bud) is an embryonic shoot located in the axil of a leaf.

B) ALL OF THE ABOVE

pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants.

C) STEMS AND ROOTS

secondary growth is the result of the activity of the two lateral meristems, the cork cambium and vascular cambium. Arising from lateral meristems, secondary growth increases the girth of the plant root or stem.
