Assertion : In cymose inflorescence, the main axis ends in a flower, but the lateral axis show continuous growth
Reason : The arrangement of flower in this inflorescence is centrifugal.

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 the assertion is false but reason is true

Text Solution

Verified by Experts

The correct Answer is:
D
In cymose inflorescence, the main axis ends in a flower and similarly the lateral axis also ends in a flower. Thus the growth of each axis is checked. In cymose inflorescence, the thermal flower is always older and opens earlier than the lateral ones, i.e., the order of opening of flowers is centrifugal.
