Answer» CELL division Cell differentiation Cell dedifferentiation Redifferentiation Solution :Cell dedifferentiation Interfascicular cambium anbd PHELLOGEN are fromed due to dediferentiation Differentiation : It is a process that leads cells TOWARDS maturity. It is called differentiation. During differentiation most of or some changes occur in PROTOPLASM and cell wall. Dedifferentiation : Differentiated cells maintain cell division capacity. This event is known as Dedifferentiation. Interfascicular cambium and cork cambium are formed from COMPLETELY differentiated parenchymatic cells. It is an example of dedifferentiation. Redifferentiation : De-differentiated cells divide once again, and lose their capacity to become adult/mature. This event is known as Redifferentiation.
