Why are flowering plants more successful in reproduction?
Their use of both flowers and seeds in reproduction distinguishes angiosperms (flowering plants) from gymnosperms, ferns and mosses and provides the source for their diversity and reproductive success. These two mechanisms have allowed angiosperms to increase both the methods of egg fertilization and the range of embryo dispersal, making them the most diverse plant group globally.Dry EnvironmentsUnlike ferns and mosses, both angiosperms and gymnosperms do not require external sources of water to transport the sperm to the egg.
