dedifferentiation

C

redifferentitation

D

development

Text Solution

Verified by Experts

The correct Answer is:
B

The living differentiated cells, that have lost the capacity to divide can regain the power of division under certain conditions, this phenomenon is termed as de-differentiation. E.g. formation of meristems-interfascicular combium (formed form outer layer of cortex) from fully differentiated parencyma cells. while doing so, such meristems/tissues are able to divide and produce cells that once again lose the capacity to divide but mature to perform specific functions, i.e., get redifferentiated. E.g., cells of secondary xylem, secondary phloem, periderm. Thus redifferentiation can be defined as maturation or differentiation of dedifferentiated tissues.
