Pteridophytes are primitive vascular plants, commonly known as ferns. Unlike other vascular plants, the life cycle of ferns is split between free-living gametophytes and sporophytes phases. The gametophyte is generally simple in structure, containing egg-producing archegonium and sperm-producing antheridium. The sporophyte phase is structurally more complex in that it has highly specialized roots, stems and vascular systems as well as sporangia in which spores are produced. Ferns are among the first vascular plants that successfully invaded terrestrial habitats. They disperse mainly by spores and are regarded more primitive than seed plants..

The Pteridophyta Divsion contains ferns. Ferns are plants with leaves, roots, and stems; but they do not have flowers like most plants.
