| Assertion : Isobilateral leaves are amphistomatic. |
| Reason : Mesophyll is not differentiated into palisade and spongy. |
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

Both the surfaces of isobilateral leaf contain stomata. The leaf, is therefore, amphistomatic. In isobilateral leaves, mesophyll is not differentiated into palisade and spongy tissues. Instead, the undifferentiated mesophyll is similar to spongy tissue.
