answered-by-expert Expert Answer

In many members of Asteraceae family such as sunflower, the sepals are modified into threadlike, hairy structures called pappus, which surround the fruit and can stick to animal fur or be lifted by the wind, aiding in seed dispersal. Thus, modification of sepals and not petals occurs to form pappus. Also, pappus aids in seed dispersal and not dispersal of the flower.
