       Interfascicular cambium and cork cambium are formed due to (a) cell division                                                                  (b) cell differentiation (c) cell dedifferentiation                                               (d) re differentiation


                      (c) Interfascicular cambium and cork cambium are formed due to cell dedifferentiation. Differentiation The process which leads to maturation of cells is called differentiation. During differentiation, a few or major changes happen in protoplasm and cell walls ofthe cells. Dedifferentiation A differentiated cell can regain its capacity for cell division undercertain conditions. This phenomenon is called dedifferentiation. Formation ofinterfascicular cambium and cork cambium from fully differentiated parenchyma cells isan example of dedifferentiation. Re differentiation A dedifferentiated plant cell once again loses its capacity to divideand becomes mature. This phenomenon is called re differentiation.
