NEETBotanyPlant - Growth and Development
Read the following Assertion and Reason and choose the correct option. Assertion: Formation of meristems – interfascicular cambium and cork cambium from fully differentiated parenchyma cells are examples of dedifferentiation Reason: Meristems are able to divide and produce cells that once again lose the ability to divide
Options
- ABoth Assertion and Reason are true and Reason is correct explanation of Assertion
- BBoth Assertion and Reason are true but Reason is not the correct explanation of Assertion
- CAssertion is true but the Reason is false
- DBoth Assertion and Reason are false
Correct answer
B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
Step-by-step solution
The living differentiated cells, that by now have lost the capacity to divide can regain the capacity of division under certain conditions. This phenomenon is termed as dedifferentiation. For example, formation of meristems – interfascicular cambium and cork cambium from fully differentiated parenchyma cells.
