Options

• Dedifferentiation

• Development

• Senescence

• Differentiation

Answer 1

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

Explanation:

Through the process of dedifferentiation, specialised leaf mesophyll cells revert to a simpler, unspecialized state. This transformation is a cornerstone of tissue culture, as these cells regain their capacity for rapid division to form a callus a disorganized mass of undifferentiated cells.
