What evolutionary advantages do Pollen, seeds, flowers, and fruits each offer?
Pollen and seeds allow genetic dispersal away from water. As plants adapted for terrestrial habitats the gametetophyte generation became smaller and self contained. This eventually became pollen able to travel by wind or be carried by a pollinator. This allows plants to use sexual recombination over long distances without water to carry the pollen. http://www.mansfield.ohio-state.edu/~sab… http://www.learner.org/channel/courses/e… Seeds have a coat for protection and endosperm (stored food) to support the plant embryo until conditions are right for germination. http://www.biologie.uni-hamburg.de/b-onl… Flowers contain an enclosed & protected ovary that will develop a seed once the egg is fertilized.
