The prothallium produces both male and female sexual organs. When the female organs become fertilized by the male organs, small fern plants begin to grow. In some ferns it can take as long as six months for the first fronds (leaves) to appear after sexual fertilization.
Alternate Dispersal Methods. Most fern spores are dispersed by wind, but they can also travel on animal fur or bird feathers. Some fern spores drop into waterways where they are swept to a new place. Fern spores might fall into an animal's food, be eaten and later dispersed in the animal's droppings.ern Propagation. You can try to propagate ferns from spores at home, as a project. The process involves picking a frond with spore sori and allowing it to dry between sheets of paper. Ripe sori should drop their spores within 24 hours.
