Unlike most plants, ferns reproduce using spores instead of seeds. Sporangium, brown spots located under a fern leaf, contains spores. When it rains, the spores are dragged from the granules where they travel to the ground, take root and grow.

Which plant structure moves water and food throughout a plant?
Apart from the bending of trees, and the blowing of leases and similar, plant cells do not ordinarily move.BUT the exception is in Ferns, which produce a motile flagellate sperm. (A mobile, sperm with a propelling tail). The Fern spores grow into a prothallus, and these exchange sperm which swim to their new home.This is why ferns prefer a moist environment, to aid the sperm in swimming.
