| 1. | The process where differentiated cells regain the ability to divide |
| 2. | The formation of specialised tissues from meristems |
| 3. | The loss of cellular contents during senescence |
| 4. | The conversion of meristematic cells into permanent tissues |
| 1. | Dedifferentiation: Formation of interfascicular cambium and cork cambium from parenchyma cells. Redifferentiation: Development of secondary xylem and secondary phloem from the cambium.
|
| 2. | Dedifferentiation: Differentiation of sieve tube elements into companion cells. Redifferentiation: Formation of primary xylem from vascular cambium. |
| 3. | Dedifferentiation: Conversion of collenchyma into sclerenchyma in response to stress. Redifferentiation: Formation of pericycle from epidermal cells. |
| 4. | Dedifferentiation: Development of root hair from epidermal cells. Redifferentiation: Formation of phloem fibers from sieve tube elements. |
Interfascicular cambium and cork cambium are formed due to
| 1. | Cell division |
| 2. | Cell differentiation |
| 3. | Cell dedifferentiation |
| 4. | Redifferentiation |
| 1. | Dedifferentiation | 2. | Differentiation |
| 3. | Redifferentiation | 4. | Development |
