the biochemical or morphological change of meristmatic daughter cell to be become a permanent cell is called

1. differentiatin
2. dedifferentiation
3. redifferentiation
4. indifferentiation

Hello Student
Correct answer is 2. dediffrentiation
The phenomenon of regenaration of permanant tissue to meristamatic tissue is called dediffertiation. Redifferentiation is maturation of dedifferentiated tissue.

The correct answer is (3) redifferentiation

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.
The cells derived from root apical and shoot-apical meristems and cambium differentiate and mature to perform specific functions. This act leading to maturation is termed as differentiation.
