Functional adaptation
Pollen coat prevents dehydration: plants
"The gymnosperms, and the flowering plants which evolved more recently, among other, much smaller groups, have developed pollen which carries the male gamete in a form protected from dehydration to special receptive structures in the female part of the flower (pollination)." (Cutler 2005:96)
