Question

Dedifferentiation process takes place during formation of which of the following tissues?

• A. Apical meristem and root cambium.
• B. Intrafascicular cambium and interfascicular cambium.
• C. Interfascicular cambium and root cambium.
• D. Only during formation of interfascicular cambium.

Answer 1

The correct option is C Interfascicular cambium and root cambium.

Interfascicular cambium is formed during secondary growth in a dicot stem. It forms a continuous ring with the fascicular cambium or vascular cambium. It is formed when parenchymatous cells of the cortical region dedifferentiate and resume meristematic activity.

Cambium is absent in roots. The secondary growth occurs by dedifferentiation of cells in the pericycle.

So, the correct answer is 'Interfascicular cambium and root cambium.'
