| Read the assertion and reason carefully: |
| Assertion : Degeneration of cells causes abscission. |
| Reason : Parenchymatous layer forms abscission layer. |
A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C) If the assertion is true but the reason is false
D) If both the assertion and reason are false
E) If the assertion is false but reason is true
Correct Answer: B
Solution :
Abscission involves formation of a special parenchymatous layer called abscission or separation layer at the base of organ and a layer of suberised thick-walled 'cork' cells called protective layer over the mother axis. Degeneration of cells of abscission or separation layer causes abscission.
