During secondary growth in dicotyledonous stems, the fully differentiated parenchymatous cells of medullary rays regain the capacity to divide and form the interfascicular cambium. This phenomenon is an example of:

Step-by-step solution

Dedifferentiation: This is the process where cells that have already matured and lost their ability to divide (like the fully differentiated parenchymatous cells of the medullary rays) regain the capacity to divide and become meristematic again. The formation of the interfascicular cambium and cork cambium are classic examples of this in plants. Differentiation is the initial process where actively dividing cells (meristems) mature and lose their ability to divide to perform specific functions. Redifferentiation ha
