Q 1 :    

Formation of interfascicular cambium from fully developed parenchyma cells is an example of                [2024]

  • differentiation

     

  • redifferentiation

     

  • dedifferentiation

     

  • maturation

     

(3)

Dedifferentiation is the process of despecialisation of differentiated living cells so that they regain the capacity of division under certain conditions, e.g., formation of interfascicular cambium and cork cambium from fully developed (differentiated) parenchyma cells.

 



Q 2 :    

In tissue culture experiments, leaf mesophyll cells are put in a culture medium to form callus. This phenomenon may be called as          [2023]

  • development

     

  • senescence

     

  • differentiation

     

  • dedifferentiation
