THE WHY. “We are not positive why double fertilization occurs. Arthur Cronquist (1971) considered double fertilization a “mere evolutionary happenstance.” One possible advantage of double fertilization is that the plant does not invest energy in seed nutritive tissue until after an egg has been fertilized. Another possible advantage is that the endosperm nucleus is very active and divides rapidly. It forms the nutritive tissue very quickly. Rapid seed development has obvious advantages.’
