How are club mosses and ferns similar?
Club mosses (Phylum Lycopodophyta) and horsetails (Phylum Equisetophyta) are similar to ferns (Phylum Pteridophyta) in that they; - do not produce seeds, only spores - have stems that are unstrengthened by wood (evolved first in the more advanced gymnosperms) - have a dominant sporophyte generation - do have vascular tissue (not as advanced as seed plants but there nonetheless) - do not produce flowers (flowers evolved first in angiosperms)

Is the sporophyte stage of a moss much larger than the gametophyte stage?
Ferns have a dominant sporophyte and a reduced gametophyte. As for moss, it depends on the type. If referring to mosses under the phylum Bryophyta (these are the nonvascular mosses) they have a dominant gametophyte. If referring to mosses under seedless vascular category, such as club mosses in the phylum Lycophyta, these plants have a dominant sporophyte and a reduced gametophyte.
