Question

Formation of interfascicular cambium from fully developed parenchyma cells is an example for

• A. Differentiation
• B. Redifferentiation
• C. Dedifferentiation
• D. Maturation

Answer 1

The Correct Option is C

When a fully developed parenchyma cell undergoes a change to regain its capacity to divide and form new tissues, a process known as dedifferentiation occurs. This is an example of how interfascicular cambium is formed in plants. Dedifferentiation is a process where mature cells revert to a meristematic state, allowing them to contribute to secondary growth by producing new vascular tissues. This contrasts with processes like:

• Differentiation: Mature cells specialize for specific functions.
• Redifferentiation: Dedifferentiated cells specialize again after reverting to meristematic form.
• Maturation: Cells achieve full form and function.

In this context, the formation of interfascicular cambium is a classic case of dedifferentiation because it involves the conversion of mature, non-dividing parenchyma cells into a meristematic state, enabling them to contribute to the formation of new tissues in the plant.
