The major distinction between dedifferentiation and redifferentiation is that dedifferentiation is the process of differentiated cells in plants regaining the ability to divide mitotically, whereas redifferentiation is the process of dedifferentiated cells losing the ability to divide.
Furthermore, dedifferentiated tissue, such as interfascicular vascular cambium, cork cambium, and wound meristem, operates as meristematic tissue, whereas redifferentiated tissue serves as functionally-specialized tissue.
Dedifferentiation and redifferentiation are two processes that occasionally affect the ability to divide through mitosis.
Dedifferentiation
Differentiated cells in a specific area of the plant body regain their ability to divide through dedifferentiation. It enables a section of the plant to generate new cells. As a result, differentiated cells are usually dedifferentiated before undergoing large physiological or structural changes.
The functional forms of the cells revert to their early developmental stages during dedifferentiation. Dedifferentiated cells thus serve as many types of meristematic tissue in plants, such as interfascicular vascular cambium, cork cambium, and wound meristem.
Furthermore, during the regeneration processes of lower life forms such as amphibians and worms, dedifferentiation is common.
Redifferentiation
is the loss of differentiated cells’ regained ability to divide. It enables differentiated cells in the plant body to operate as functionally specialised cells. The treated differentiated cells revert to the redifferentiated form, performing a specific function, after preparing the plant body for physiological or structural change by dedifferentiation.
After cell division, the dedifferentiated vascular cambium, for example, redifferentiates into secondary xylem and phloem. The cells of the secondary xylem and secondary phloem, on the other hand, are incapable of further cell division, and after maturation, these cells execute duties such as food and water conduction while maintaining the structural integrity of the plant.
Similarities between Dedifferentiation and Redifferentiation
- Cells change their ability to divide through two mechanisms: dedifferentiation and redifferentiation
- Both processes occur in differentiated cells
- Both systems are also important in the genesis and healing of damage
Difference between Dedifferentiation and Redifferentiation
| Process | Dedifferentiation | Redifferentiation |
| Definition |
Dedifferentiation is the process through which mature cells revert to their pluripotent state And become pluripotent. |
Dedifferentiated cells lose their ability to divide and become specialised to perform a role by converting into a part of the permanent tissue during redifferentiation. |
| Outcome | Dedifferentiation allows cells to regain their ability to divide further. | Due to redifferentiation, fresh cells lose their ability to differentiate further. |
| New Cells | Dedifferentiation creates new cells that serve as meristems for future differentiation. | Secondary structures emerge from redifferentiated cells and perform specialised roles. |
| Examples | of Dedifferentiated tissues include cork cambium and inter-fascicular cambium. | Redifferentiated tissues include secondary xylem, secondary phloem, and phelloderm tissue. |
Conclusion
Dedifferentiation is the process through which differentiated cells regain the ability to divide mitotically. As a result, the dedifferentiated tissue in the plant body functions as distinct meristematic tissue. As a result, this mechanism is critical for the generation of new cells at a specific site. Redifferentiation, on the other hand, is the loss of differentiated cells’ recovered ability to divide. It enables functional specialisation of these cells, allowing them to execute a specific purpose inside the plant. The influence on the differentiated cells’ ability to divide is the major difference between dedifferentiation and redifferentiation.
