to reproduce sexually, bryophytes and ferns require...
heterospory

Bryophytes and ferns have flagellated sperm that need free - water to swim to the eggs for sexual reproduction. Heterospory is not a requirement for their sexual reproduction. High temperatures are not necessary for their sexual reproduction process. They do not rely on insect - based pollination as they are non - flowering plants.
