They aren't - Moses was a human, dude!
You mean mosses :-)
An early developmental stage in the gametophyte of both mosses and ferns (immediately following the meiospore) is called the Protonema.
The cells of the gametophyte stage are haploid in both species.
Gametophytes of both species reproduce by mitosis to form gametes including a flagellated sperm (biflagellated in the case of Mosses).
Sperm of both species need to swim to the ovum to fertilize the ovum in both species (and hence need water - the point of the other poster here) and once the fertilization occurs, the plant has diploid cells.
