Question

Cork, secondary cortex and secondary xylem are formed through:

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

Answer 1

The correct option is B Redifferentiation

Redifferentiation is the formation of new or differentiated tissue from already differentiated tissue. During this process, cells of parenchymatous tissue undergo dedifferentiation to meristematic tissue. The cells cut off by the meristematic tissue based on the location and function get modified to respective tissues like secondary cortex, secondary xylem and secondary phloem in roots, monocot stem, cork cells, etc.
