Question

__________ are the examples of tissues, formed by dedifferentiation.

• A. Interfascicular cambium
• B. Cork cambium
• C. Both (a) and (b)
• D. Tracheary elements

Answer 1

Answer: (C)

Both (a) and (b)

Interfascicular cambium is the cambium formed by dedifferentiation of cells forming the ground tissue (parenchyma) that lie in line to the vascular cambium, since these strips of cambium originate between two vascular bundles or connect two vascular cambia together they are referred to as the interfascicular cambia. They are responsible for producing medullary rays during secondary growth.

Cork cambium also develops from dedifferentiation of cells forming the ground tissue, here the cambium originates in the cortex to produce the secondary cortex and the cork.

So, the correct answer is 'Both (a) and (b)'
