-
In tissue culture experiments, leaf mesophyll cells are put in a culture medium to form callus. This phenomenon may be called as:
Differentiated cells regaining the capacity to divide is dedifferentiation.
The living differentiated cells, that by now have lost the capacity to divide can regain the capacity of division under certain conditions. This phenomenon is termed as dedifferentiation. Same occurs in tissue culture of leaf.
2022 Phase 2 1 question
-
The phenomenon by which the undividing parenchyma cells start to divide mitotically during plant tissue culture is called as:Living differentiated cells that had lost the capacity to divide regaining the capacity of division (e.g. parenchyma cells in tissue culture forming callus) is called dedifferentiation.
