| Other aberrant gametophyte phenotypes were observed among the group of mutants that could form antheridia. |
| Since the asexual gametophyte does not form antheridia or archegonia, crosses to confirm its genotype could not be performed. |
| For example, in mosses the sporophyte is a capsule atop a slender stalk that grows out of the top of the gametophyte. |
| Many algae are characterized by an alternation of haploid gametophyte and diploid sporophyte generations. |
| It is believed that the gametophyte generation also had water-conducting tissue, cuticle, and stomata, making this species isomorphic. |
| The sporogenous cells of the ovary lead to the production of the female gametophyte or embryo sac that contains the egg cell. |
