Dedifferentiation is the process that mature cells reverse their state of differentiation and acquire pluripotentiality. Redifferentiation is the process where dedifferentiated cells lose the power of division and become specialized to perform a function by converting into a part of the permanent tissue. Outcome. See more In plants, differentiation is the process where cells derived from root apical and shoot-apical meristems and cambium differentiate and mature to perform specific functions. Once differentiated, the living plants cells lose … See more Plants cells are derived from meristems of shoot apex, root apex, and cambium by a process known as differentiation where cells get … See more Once new cells are formed from the dedifferentiated tissues that act as meristems, the cells lose their ability for further division and … See more Under certain conditions, plants cells that are already differentiated and lost the ability of further division regain the capacity of division … See more
