The meaning of GAMETOPHYTE is the haploid, multicellular, sexual reproductive stage in plants and algae that develops from spores and that gives rise to the male and female gametes which unite during fertilization to form the zygote. How to use gametophy

Here the notion of two generations is less obvious; as Bateman & Dimichele say "porophyte andgametophyteeffectively function as a single organism". WikiMatrix Once its spores disperse and germinate, they in turn, producegametophytes, which turn around to produce another sporophyte generation and so...

Fern - Sporangia, Gametophytes, Alternation: The sex organs of ferns are the antheridium and the archegonium. Within the archegonial venter the zygote undergoes cell divisions to form the embryo, which usually has a development distinctive to ferns. Stem

Fern gametophytes are autotrophic and independent of sporophytes, and they develop pluripotent meristems that drive prothallus development and sexual reproduction. To reveal cellular dynamics during meristem development in fern gametophytes, we performed long-term time-lapse imaging and determined the real...
The gametophytes of all species are dorsiventral, axial structures, which can be straight, curved, narrow, or wide. Paraphyses and gametangia form on the dorsal surface and rhizoids on the ventral surface. The apical meristem is overarched by immature dorsal tissue. Minor differences in the ...
Ceratopteris richardii is a model fern species widely used to analyze various developmental processes and their regulation in gametophytes. The form of mature C. richardii gametophytes depends on the activity of the marginal meristem, but knowledge on meristem formation and structure is limited. Theref...
