\tThe pteridophytes are found in cool, damp, shady places.\tThe main plant body is a sporophyte which is differentiated into true root, stem and leaves, possess well-differentiated vascular tissues.\tThe sporophytes bear sporangia that are subtended by leaf-like appendages called\xa0sporophylls, which may form distinct compact structures called\xa0strobili or cones.\tThe sporangia produce spores by meiosis in spore mother cells, the spores germinate to give rise to thalloid gametophytes called\tThe gametophytes bear male and female *** organs called\xa0antheridia and archegonia, respectively.\tWater is required for transfer of antherozoids to the mouth of archegonium and fusion of male gamete with the egg present in the archegonium result in the formation of zygote.\tZygote produces a multicellular well-differentiated sporophyte which is the dominant phase of the pteridophytes.
