NEET BIOLOGY

Detailed explanation-1: -This occurs within the cell lineage. This phenomenon occurs due to change in the gene expression pattern, shape and protein expression pattern. Interfascicular cambium and cork cambium are the examples of tissues formed by dedifferntiation.

Detailed explanation-2: –The formation of cork cambium from fully differentiated parenchyma cells is an example of dedifferentiation.-Dedifferentiation is the process by which a cell shows regression from a specialised state to a cell having a simpler state. This means that the cell loses certain characteristics and functions.

Detailed explanation-3: -The formation of secondary meristems; interfascicular cambium and cork cambium from differentiated parenchyma cells is dedifferentiation.

Detailed explanation-4: -of dedifferentiated tissue is the cork cambium or phellogen, that develops in the cortex region while secondary growth forms cork or phellem on outer side and secondary cortex or phelloderm towards the inner side.

Detailed explanation-5: -Solution : Both interfascicular cambium and cork cambium are the examples of tissues formed by dedifferentiation.
