WebGametophyte. The dominant generation in bryophyte is gametophyte. The vegetative plant body is a gametophyte. It has smaller size. Plant body: The plants are multicellular. They have simple thallus. Some may be differentiated into simple leaves and stem. Vascular tissues (xylem and phloem) are absent. Roots are absent. WebThe bryophyte embryo also remains attached to the parent plant, which protects and nourishes it. This is a characteristic of land plants. The bryophytes are divided into three phyla: the liverworts or Hepaticophyta, the hornworts or Anthocerotophyta, and the mosses or true Bryophyta.

WebChapter 29 Homework. Nonvascular plants (informally called bryophytes) generally live very close to the ground, sprawling out rather than growing upward. This growth form is due to their thin body parts and lack of vascular structures that would support upward growth. Three phyla of bryophytes exist today: liverworts, hornworts, and mosses. 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.
