Question

Interfascicular cambium and cork cambium are formed due to

• A. Cell division
• B. Cell dedifferentiation
• C. Cell differentiation
• D. Redifferentiation

Answer 1

The correct option is B Cell dedifferentiation

Cell division is the process in which one cell divides to form two new daughter cells.

Cell differentiation is the process in which a meristematic cell differentiates to have a fixed shape and starts to perform its function.

Cell dedifferentiation is the process in which a differentiated cell becomes meristematic again and gains the ability to divide.

Redifferentiation is the process in which a dedifferentiated cell again differentiates and starts to perform its function and attains a fixed shape.

Interfascicular cambium and cork cambium

• Interfascicular cambium is a continuous ring formed by the meristematic activity of the cells of medullary rays present next to intrafascicular cambium.
• Cork cambium is a meristematic tissue which divides and replaces the broken cells of epidermal and cortex layer due to the high activity of vascular cambium.

Interfascicular cambium and cork cambium are formed due to cell dedifferentiation.

Final answer: Option c. Cell dedifferentiation.
