Differentiation, dedifferentiation, redifferentiation
- The cells derived from root apical and shoot-apical meristems and cambium differentiate and mature to perform specific functions, termed as differentiation.
- During differentiation, cells undergo few to major structural changes and also develop a very strong, elastic, lignocellulosic secondary cell walls, to carry water to long distances.
- The living differentiated cells that have lost the capacity to divide can regain the capacity of division under certain conditions, termed as dedifferentiation.
For example, formation of meristems – interfascicular cambium and cork cambium from fully differentiated parenchyma cells.
- Some meristems/tissues divide and produce cells that once again lose the capacity to divide but mature to perform specific functions, termed as redifferentiation.
