Bryophytes, their chemistry and chemical taxonomy
WebDescription. Like all bryophytes, the dominant life phase of a hornwort is the haploid gametophyte.This stage usually grows as a thin rosette or ribbon-like thallus between one and five centimeters in diameter. … WebBryophytes are small and structurally simple plants consisting of around 20,000 species distributed in three evolutionary lineages (mosses, liverworts, and … 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 … 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 … See more Traditionally, all living land plants without vascular tissues were classified in a single taxonomic group, often a division (or phylum). As early as 1879, the term Bryophyta was used by German bryologist Wilhelm Schimper to describe a group containing all three … See more Environmental • Soil Conditioning • Bioindicators • Moss gardens See more The defining features of bryophytes are: • Their life cycles are dominated by a multicellular gametophyte stage • Their sporophytes are unbranched • They do not have a true vascular tissue containing lignin (although some have specialized tissues for the transport of … See more Like all land plants (embryophytes), bryophytes have life cycles with alternation of generations. In each cycle, a haploid gametophyte, each of whose cells contains a fixed number of unpaired chromosomes, alternates with a diploid sporophyte, … See more There have probably been several different terrestrialization events, in which originally aquatic organisms colonized the land, just within the lineage of the Viridiplantae.
