Question

The phenomenon of dedifferentiation is

• A. regaining the capacity to divide mitotically by differentiated cells
• B. the event of losing the ability to divide by dedifferentiated cells
• C. regaining the capacity to divide meiotically by differentiated cells
• D. regaining the capacity to divide meiotically by redifferentiated cells

Answer 1

Answer: (A)

The living differentiated cells that have lost the capability to divide can regain the capacity of the division under certain conditions; this phenomenon is called dedifferentiation. It occurs during secondary growth when permanent cell-like parenchyma regains the power of division to form vascular cambium and cork cambium. The redifferentiation is the event of losing the ability to divide by dedifferentiated cells.
