What is the best description best firs seedless vascular plants?

Seedless vascular plants are a group of plants that possess vascular tissue for the transport of water and nutrients but reproduce via spores instead of seeds. This group includes ferns, horsetails, and clubmosses. They typically thrive in moist environments and exhibit a dominant sporophyte generation, with the gametophyte being a smaller, independent structure. Their life cycle is characterized by the alternation of generations, where both the sporophyte and gametophyte stages play essential roles in reproduction.
