adaptations of Pteridophytes not seen in Bryophytes   vascular, life cycle dominated by the sphoryte stage  
🗑
dominant stage of the fern life cycle   sporophyte stage  
🗑
significance of the seed   protection for the embryo, stored nutrients for growth of embryo, and adaption for reproduction in diverse terrestrial environments  
🗑
