Sporophyte, which literally means "spore-bearing" plant, is the diploid multicellular phase of an organism that displays alternation of generations. The sporophyte phase develops from the fertilized egg, or zygote, by simple cell division...

A sporophyte is the diploid (i.e., it is 2n, having two sets of chromosomes), spore-producing generation in the life cycle of plants. A sporophyte is formed by the fusion of two haploid gametes (or gametophytes, these have one set of chromosomes, i.e.,...

All land plants, and some algae, have life cycles in which a haploid gametophyte generation alternates with a diploid sporophyte, the generation of a plant or alga that has a double set of chromosomes. A multicellular sporophyte generation or phase is...

Questions concerning the two competing theories of the development of alternating generations in land plants, the homologous theory and the antithetic theory, have never been fully resolved. In the majority of recent accounts there appears to have been increasing de facto support (if one...

Recent research on the developmental anatomy and morphology of the fern sporophyte is reviewed. Detailed histological and experimental studies of the organization of the fern shoot apical meristem have reconfirmed the recently controversial role of the shoot apical cell as the single apical initial...
