| Which among the following is not a single flower but a group of flowers?

A. Datura

B. Rose

C. China rose

D. Sunflower

Right Answer is: D

SOLUTION

The sunflower is not a single flower at all, but a group of flowers. It is packed with a hundred or more small flowers in a structure known as a head. The head is a series of greenish bracts called phyllaries (little leaves). Next to the phyllaries are the ray flowers. Normally ray flowers produce seeds, but the ray of the sunflower is sterile and serves only to attract insects.
