WebOct 8, 2024 · In this virtual issue of the Journal of Plant Research, we have compiled a list of 19 recent papers published in this journal that have contributed to the modern understanding of pteridophyte ecology and evolution.These include papers in the areas of: (1) breeding systems, (2) species complexes and polyploidization, (3) fossil taxa, (4) gametophyte … WebIn bryophytes, gametophyte is dominating. In pteridophytes, the sporophyte is dominating. Sporophytic phase: The sporophytic phase depends completely on gametophytic. The sporophytic phase is an independent autotrophic. Cell type: Bryophytes has haploid cells. Pteridophytes have diploid cells. Examples: Mosses, liverworts, hornworts.

WebMajority of the Pteridophytes are homosporous e.g., Lycopodium, Pteris etc. Spores on germination produce monoecious gametophyte. Some Pteridophytes are heterosporous and produce two types of spores: microspores and megaspores.
