Bryophyte zygotes develop into embryos
Webembryo undergoes mitotic division into a functioning diploid multicellular organism, a processcalled matrotrophy. Generalized Alternation of Generations. Note the position, timing and importance of meiosis and mitosis. Bryophyte zygotesdevelop in a distinctive, multicellulararchegonia. WebThe algae reproduce by vegetative, asexual and sexual methods. Vegetative reproduction is by fragmentation. Each fragment develops into a thallus. Asexual reproduction is by the production of different types of spores, the most common being the zoospores. They are flagellated (motile) and on germination gives rise to new plants.

WebAll embryophytes (‘land plants’; a term that includes mosses, liverworts, ferns, and all seed-bearing plants) have bodies that are partitioned into numerous cells, each cell being …
WebIt is generally assumed that retention of the zygote and delay in meiosis led to matrotrophic embryo development and intercalation of the diploid sporophyte before spore production. However, new data on the cell biology of sporogenesis in extant bryophytes suggest that spores were produced directly from zygotes in protoembryophytes. WebThe zygote develops into a long and slender sporophyte that eventually splits open, releasing spores. Thin cells called pseudoelaters surround the spores and help propel them further in the environment. Unlike the …

Thin cells called pseudoelaters surround the spores and help propel them further in the environment. Unlike the elaters observed in horsetails, the hornwort pseudoelaters are single-celled structures.
