What is Redifferentiation?

The process by which a cell or tissue, having lost its specialized characteristics and capacity for division (dedifferentiated), reacquires them to perform a specific function.

Key points

  • Understand the process of redifferentiation in plant tissues.
  • Differentiate redifferentiation from differentiation and dedifferentiation.
  • Identify examples of redifferentiation in plant development.
  • Appreciate the role of redifferentiation in plant tissue culture and regeneration.

Common exam trap

Confusing redifferentiation with differentiation.

Definitions

Redifferentiation

Meaning

The process by which a cell or tissue, having lost its specialized characteristics and capacity for division (dedifferentiated), reacquires them to perform a specific function.

Term

Dedifferentiation

Meaning

The process by which a differentiated cell loses its specialized characteristics and re-enters the cell cycle to divide.

Practice preview

  • Consider a scenario where a plant tissue culture is initiated from a mature parenchyma cell. This cell first forms a callus, and then specific hormones are added to induce the formation of roots and shoots. The cells for
