Question

All of the following are formed from dedifferentiation of parenchyma cells, except Choose answer: Wound cambium Cork cambium Interfascicular cambium Intrafascicular cambium

Answer 1

From which chapter it was

Answer 2

Answer:

Intrafascicular cambium

Explanation:

• A cellular process in which a living dedifferentiated cell that has otherwise lost the ability to divide, can regain the capacity of cell division under specific conditions refers to the de-differentiation.
• For example; the formation of meristems i.e-interfascicular cambium (formed from medullary rays)  and the cork cambium (formed from the outer cortex layer) from fully differentiated parenchyma cells, which have already undergone differentiation.

• The formation of wound meristem is often inducible as induced by injuries. In response to any wound or injury, wound meristems are derived from any primary permanent tissue during the secondary growth- abnormal secondary growth. This is a lateral meristem that lies along the sides of plants and contributes to increased girth.

• Intrafascicular cambium originates from procambium i.e. from embryonic cell origin and thus is primary.

Since all the three above-mentioned cambiums have originated from dedifferentiation permanent tissue-parenchyma, intrafascicular cambium is the correct answer.
