A fern, or Polypodiopsida, is a type of vascular plant (one with xylem and phloem) that reproduces by spores rather than seeds or flowers. They vary from mosses and other bryophytes in that they are vascular, meaning they have specialized tissues that conduct water and nutrients, and they have branched sporophyte life cycles. Megaphylls, the complex leaves of ferns, are more complex than the microphylls of clubmosses. Fiddleheads are produced that uncoil and develop into fronds. There are around 10,560 known living species in this category. Ferns are described as all members of the Polypodiopsida family, which includes both leptosporangiate and eusporangiate ferns, with the latter group encompassing horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns, among others.
