Question

Where did dissemination occur in "lower" plants? During the gametophyte or during the sporophyte generation?

Answer 1

These plants would have been spread during the sporophyte generation because the spores could blow away. When the gametophytes reproduced, the sperms swam to the eggs, but the eggs stayed in the archegonia where they were produced on the female gametophyte. So the sporophyte grows directly from the female gametophyte and can't grow anywhere else.
