Homosporous and Heterosporous ferns

Homosporous pteridophytes: produce only one type of spore that contains both male and female parts.
The resulting gametophyte is monoecious that is both antheridia and archegonia are present on the same plant
Eg: Lycopodium, Equisetum
LycopodiumEquisetum






















Heterosporous pteridophytes: Produce two types of spores or distinct male and female spores or microspore and megaspores. The resulting gametophyte is dioecious. Microspore germinate to form male gametophyte that bears antheridia. Megaspore germinate to form female gametophyte that bears archegonia
Selaginella
Eg: Selaginella, Marselia
