Male and Female spores don't get together and "mate". The spore is
released into the wind and dispersed. It lands and grows into a
gametophyte, a small heart-shaped tissue with 'male' and 'female'
tissues. Here 'n' gametes are formed. The male gamete swims to the
female site and fuses to form a '2n' zygote. The zygote sprouts to
form the traditional fern. The gametophyte stage is hard to find. Try
looking under leaf litter in a stand of ferns. This swimming of the
male gamete is the main reason ferns are found in moist areas.
