CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -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. For example, formation of meristems; interfascicular cambium and cork cambium from fully differentiated parenchyma cells.

Detailed explanation-2: -Dedifferentiation is a cellular process by which cells grow in reverse, from a partially or terminally differentiated stage to a less differentiated stage within their own lineage. In general, the phenomenon is manifested by a change in the shape, gene expression pattern, protein expression pattern and function.

Detailed explanation-3: -Living differentiated cells which have otherwise lost the capacity to divide, can regain the power of division under certain conditions.

Detailed explanation-4: -Differentiation: Formation of tracheary elements. Dedifferentiation: Formation of vascular cambium and cork cambium (meristems) from fully differentiated meristems. Redifferentiation: Formation of secondary xylem and phloem from dedifferentiated cells of the cambial ring.

Detailed explanation-5: -The living differentiated cells, that have lost the capacity to divide can regain the power of division under certain conditions, this phenomenon is termed as de differentiation.
