	PTERIDOPHYTA - LoveToKnow Article on PTERIDOPHYTA
		The Ferns form the great majority of existing Pteridophytes; the importance and interest of the other groups, of which the Club-mosses and Horsetails are the most familiar examples, depend largely on the fact that they are the surviving representatives of large families of plants which flourished in earlier geological periods.
		As the result of fertilization of an ovum produced by this, the fern plant (sporophyte, asexual generation) originates; from it spores are ultimately set free, with the germination of which the life-history again commences.
		The point common to all Pteridophyta is that from the first the gam~tophyte is an independent organism, while the sporophyte, though in the first stages of its development it obtains nutriment from the prothallus, becomes physiologically independent when its root develops.

	Fern - Wikipedia, the free encyclopedia
		A fern, or pteridophyte, is any one of a group of some twenty thousand species of plants classified in the Division Pteridophyta, formerly known as Filicophyta.
		A fern is defined as a vascular plant that does not produce seeds, but reproduces by spores to initiate an alternation of generations.
		The Ophioglossophytes were formerly considered true ferns and grouped in the Family Ophioglossaceae, but were subsequently found to be more distantly related.

		So sind alle Pteridophyta (und die sich von ihnen ableitenden Spermatophyta sowie die Moose) vielzellig, sie enthalten grüne Plastiden, außerdem findet man bei ihnen ausschließlich Oogamie.
		Der Grund hierfür liegt in der Wasserabhängigkeit der männlichen Gameten der Pteridophyta (und der Bryophyta), da Wasser für ihre Fortbewegung benötigt wird, und die deshalb außerhalb aquatischer Lebensräume keine großen Entfernungen überbrücken können.
		Bei den Pteridophyta findet man Leitgewebe mit Phloem und Xylem, sekundäres Dickenwachstum, Mesophyllgewebe in Blättern mit Palisaden- und Schwammparenchym sowie eine Epidermis mit Spaltöffnungen.
