Ferns are seeded seedless non vascular vascular plants. The plant body is a gametophyte sporophyte which is differentiated into stem, leaves and rhizoids roots. Ferns once dominated the earth in tertiary carboniferous period. Young stem leaves shows circinate ptyxis. Parts of stem, young leaves, petiole are covered with hairs or scales called sori ramenta. The fertile leaves containing sporangia are called prothallus sporophylls.
