As a group of plants, ferns are not of great economic value. Many different species have been used as a minor food source and for medicine in various parts of the world. Edible fern crosiers (young leaves with coiled hook-shaped tips) are popular in some areas. The ostrich fern (Matteuccia) of northeastern North America is frequently eaten, apparently with no ill effect, but the two ferns most commonly consumed in East Asia (Osmunda and Pteridium) have been shown to be strongly carcinogenic. The minute aquatic mosquito fern (Azolla) has become a valuable plant, especially in Southeast Asia; a blue-green algae (Anabaena azollae) is always found in pockets on the leaves of Azolla and helps convert nitrogen to a form usable by other plants (see nitrogen-fixation), thus greatly increasing the productivity of rice paddies where the fern occurs. The greatest economic value of ferns has been in horticulture, with large nurseries supplying millions of plants annually for both indoor decoration and outdoor gardens and landscaping. On the negative side, the poisonous bracken (Pteridium aquilinum), which often spoils the grazing value of various lands, is considered a noxious weed in many countries.
A major value of ferns is in biological research, for they have retained a primitive life cycle involving two separate and more or less independent generations, or growth phases, the plants of which are wholly different in many respects. Water ferns (genus Ceratopteris), which have relatively short life cycles and for which many mutations have been characterized, have become model organisms for genetics teaching and research.

The typical fern, a sporophyte, consists of stem, leaf, and root; it produces spores; and its cells each have two sets of chromosomes, one set from the egg and one from the sperm. The sporophyte of most ferns is perennial (it lives for several years) and reproduces vegetatively by branching of the rootlike underground stem, or rhizome, often forming large, genetically uniform colonies, or clones. A few ferns propagate by root proliferations, and some, especially in the wet tropics, reproduce by leaf proliferations.
The spores are haploid; that is, they have one set of chromosomes. They are produced in specialized organs—the spore cases, or sporangia—on the fern leaves (fronds). Once released, the spores are carried by wind currents, and a small percentage of them fall in appropriate germination sites to form the sexual plants, or gametophytes. In ferns the gametophytes are commonly referred to as prothallia, and they are best known to biologists as laboratory objects in artificial culture. They are rarely observed in nature without arduous searching, and the gametophyte stage of the majority of fern species has never been seen in the wild.
Jan 28, 2017 · Ferns are an important phytogenetic bridge between lower and higher plants. Historically they have been used in many ways by humans, including as ornamental plants, domestic utensils, foods, and in handicrafts. In addition, they have found uses as medicinal herbs.
