WebBryophyte and fern spores are haploid cells dependent on moisture for rapid development of multicellular gametophytes. In the seed plants, the female gametophyte consists of … Web1) Which stage of the life cycle does a bryophyte prefer? Gametophyte generation, which is the photosynthetic portion of the lifecycle of real bryophytes, is, according to Rye at et al. (2016), the most dominating phase of the bryophyte life cycle. In other words, the haploid gametophyte grows from the sporophytes to produce additional haploid gametes, which …

Ferns (Pteridophytes: Seedless, Vascular Plants) – Chapter 22 The pteridophytes have more complex structure supported by an expanded vascular system compared to the lycophytes. However, the reproductive process of pteridophytes is similar to the lycophytes with separate, free-living gametophytes and the sporophyte being the dominant ...
The Bryophyta s.l. are a proposed taxonomic division containing three groups of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses. Bryophyta s.s. consists of the mosses only. They are characteristically limited in size and prefer moist habitats although they can survive in drier environments. … See more The term "Bryophyta" was first suggested by Braun in 1864. G.M. Smith placed this group between Algae and Pteridophyta. See more Bryophytes exist in a wide variety of habitats. They can be found growing in a range of temperatures (cold arctics and in hot deserts), elevations (sea-level to alpine), and moisture (dry deserts to wet rain forests). Bryophytes can grow where vascularized plants … See more Traditionally, all living land plants without vascular tissues were classified in a single taxonomic group, often a division (or phylum).
