WHAT ARE THE TYPICAL DIFFERENCES BETWEEN DIFFERENTIATION ,DEDIFFERENTIATION AND REDIFFERENTIATION?  EXPLAIN
 

Differentiation:

Differentiation is the process of development and maturation of a cell to perform a specialized function. 

In plants, the cells which are derived from the root apical, shoot apical meristems and cambium differentiate themselves and gets mature to perform a specific function. Cells loose their ability to divide once they get differentiated.

Dedifferentiation:
Dedifferentiation refers to the process in which the differentiated cells who had lost the capacity to divide, regain their dividing
capacity in certain suitable conditions. Therefore, these cells have the capability to divide. 

For example: cork cambium is developed from fully differe.tiated parenchyma cells.

Redifferentiation:
When dedifferentiated cells again mature and differentiate to perform a specialized function, the process is termed as redifferentiation. These cells again loose their ability to divide.
