The nature of sporophyll in pteridophytes:
(a) Sporangia are on the lower surface of the reproductive leaves as yellow or brown spots or sori.
(b) These are arranged like pearls on the lower surface.
© The spore-bearing leaves are called sporophylls.
(d) The sori bear groups of sporangia, which are full of spores.
(e) The plant body exhibits sporophyte and is diploid (2n).
(f) The spores formed after meiosis are haploid (n).
(g)They are dispersed through a special mechanism present in the sporangium.
(h)It may be eusporangiate or leptosporangiate
