79. Parachute mechanism of fruit and seed dispersal is due to structure called a.hooks b.pappus c.bracts d.corolla
Correct option is D) The fruit type in the Asteraceae is an achene. Dispersal of the fruits is often facilitated by the pappus (modified sepals). The pappus is quite variable, consisting sometimes of scales or bristles of some sort (or be lacking altogether). The most frequent form a pappus takes is to be tufts of hair-like bristles that act like a parachute/hang glider sort of thing to enable wind dispersal.
