Options

  1. AOnly 1 is correct
  2. BBoth 1 and 2 is incorrect
  3. COnly 3 is correct
  4. DAll are correct

Correct answer

D. All are correct

Step-by-step solution

The living differentiated cells that 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. While doing so, such meristems/tissues are able to divide and produce cells that once again lose the capacity to divide but mature to perform specific functions, i.e., get redifferentiated.
