Question
What is differentiation and redifferentiation?
✓
Answer
- It is the maturation of cells derived from the apical meristem of the root and shoot. A permanent change in the structure and function of cells leading to maturation is called differentiation.
- During cell differentiation, the cell undergoes few to major anatomical and physiological changes. For example, Parenchyma in hydrophytes develops large schizogenous interspaces for mechanical support, buoyancy, and aeration.
- The maturation is at the cost of the capacity to divide and redivide.
The cells produced by dedifferentiation once again lose the capacity to divide and mature to perform specific functions. This is called redifferentiation. For example, secondary xylem and secondary phloem are formed from dedifferentiated cambium present in the vascular bundle.
