Question

Assertion a. In syconus type of fruit, the achenes formed are fewer than total number of flowers in the inflorescence.
Reason r. Upper and middle flowers do not develop into fruits

• A. Both a and r are correct with r being correct explanation of a
• B. Both a and r are true but r is not correct explanation of a
• C. a is true but r is false
• D. a is false but r is true.

Answer 1

The correct option is A Both a and r are correct with r being correct explanation of a

In synconus type of fruit, only the female flowers within the closed receptacle (lower fleshy part) of inflorescence develop into achenes (fruitlets) whereas the upper and middle flowers do not develop into fruits. Thus, the total number of achenes formed is less than the total number of flowers within the inflorescence.

The correct answer is 'both a and r are correct with r being correct explanation of a'
