the  number of pollen grains produced by each head inflorescnce of family asteraceae  which has 10 actinomorphic flowers if each anther produces 20 pollen grains ,options are    1)300   2)100   3)500   4)1000

Dear student

Please refer the solution below for the said query

The correct option is (4).

In Asteraceae, each flower contains 5 stamens and hence 10 actinomorphic flowers will have 50 stamens.

Since each stamen produces  20 pollens, therefore 50 stamens will produce 50 x 20 = 1000 pollens. 



Hope this information clears your doubt about the topic.
