Moss gametophytes

Thu Apr 11 08:42:49 EST 1996

I got stumped on a question in class today.  I was asked how does a
developing moss gametophyte "know" whether to form an antheridium or an
archegonium.  I know some mosses are monoecious and others are dioecious.
What determines the type in unisexual gametophytes?  I assume all
gametophyte plants that develop from the same protonema produce the same
type of reproductive structure?
Thanks for any help!
