The phylum of Pterophyta is home to over 20,000 species of plants including ferns and is part of the kingdom, Plantae. Pterophyta has been in existence for over four hundred million years and provides a link between bryophytes and gymnosperms in the phylogenetic tree. Pterophyta are vascular plants which have true leaves and has a life cycle referred to as “alternation of generations”. Like Sphenophyta, Pterophyta use spores to reproduce instead of seeds and contain a free living gametophyte. Finally, this class of phylum can be found in a variety of habitats including mountains, deserts, and bodies of water.
