| After 8 to 9 weeks, archegonia had developed on the lower surface of the gametophytes just behind the growing apex. |
| It is concluded that mosses suffer detrimental effects after exposure to Asulox at concentrations similar to those that affect fern gametophytes such as bracken. |
| The surface wall of Tmesipteris gametophytes does not have the appearance of a suberized wall. |
| The haploid phase begins when the mature organism releases many spores, which then germinate to become male or female gametophytes. |
| These independent haploid plants are gametophytes that produce gametes mitotically. |
| The gametes are isogamous or anisogamous and are produced from the plurilocular sporangia of gametophytes. |
