Ferns are plants, they lack motion.
I'm not sure about horsetails, but ferns don't have flowers or seeds.

"They have spores. These are not an exact counterpart to seeds however, they are produced asexually (require no fertilization) as ferns have a 2 stage reproductive cycle."~ Hach on Answers.com
Because ferns (Pteridophyta) and gymnosperms are part of the larger category of vascular plants (Tracheophyta) and share common features that mosses lack. Perhaps also because of the spurious notion that "seed ferns" (Pteridospermatophyta), the ancestors of the gymnosperms, evolved from ferns. In fact, "seed ferns" are a large, heterogeneous category of plants which are generally believed to be only distantly related to true ferns.
Mosses are non-vascular plants whereas ferns are vascular. In ferns Sporophyte is dominant but in mosses gametophyte is dominant generation. Ferns have definite roots but in mosses leaves and roots are mostly false.
Ferns lack the flowers or seeds of the angiosperms. Instead they reproduce by forming spores in two phases, the sporophytic and a gametophytic phase. The second, gametophytic, phase is actually a free-living organism, not a seed.
