Hornworts are a group of non-vascular Embryophytes (land plants) constituting the division Anthocerotophyta ( / ˌænθoʊˌsɛrəˈtɒfətə, - təˈfaɪtə / ). The common name refers to the elongated horn-like structure, which is the sporophyte.
Anthocerotophyta. The hornworts. Most people are unaware of hornworts, though they are a quite common and widespread group of plants which may be found in tropical forests, along streamsides, and in disturbed fields around the world.
hornwort, (division Anthocerotophyta), any of about 300 species of small nonvascular plants. Hornworts usually grow on damp soils or on rocks in tropical and warm temperate regions. The largest genus, Anthoceros, has a worldwide distribution. Dendroceros and Megaceros are mainly tropical genera.
However, hornworts are discussed first in this chapter due to their strictly thalloid gametophyte morphology. Figure 2.5.2.1.1 2.5.2.1. 1: Hornworts growing in a cluster. The gametophytes are the leafy green material growing closer to the surface. The sporophytes are the emergent structures.
Hornworts are a group of bryophytes, or non-vascular plants, comprising the division Anthocerotophyta. The common name refers to the elongated horn-like structure, which is the sporophyte. The flattened, green plant body of a hornwort is the gametophyte plant.
Anthocerophyta. Quick Reference. A phylum comprising about 100 species of simple nonvascular plants, the hornworts (or horned liverworts), found worldwide in temperate and tropical regions on tree trunks, riverbanks, and other damp locations.
Jan 18, 2024 · Hornworts, Phylum Anthocerotophyta. The name Anthocerotophyta means 'horn flower plant'. These strange plants, called the hornworts, get their name from the horn-like sporophytes they produce.
The hornworts, formally known as Anthocerotae, are a monophyletic group comprising a third extant lineage of nonvascular land plants. Hornworts are similar to the thalloid liverworts in gametophyte morphology and are found in similar habitats.
Aug 13, 2020 · Hornworts comprise the division Anthocerotophyta, the name of which is derived from three Greek words: άνθος/anthos (meaning flower), κέρας/ceras (meaning horn) and φυτό/phyto (meaning plant) and refers to the horn-like shape of the hornwort sporophyte (the multicellular diploid phase of the life cycle).
Jun 16, 2020 · Page ID. Gametophyte Morphology: Exclusively thalloid, often with compartments of mutualistic cyanobacteria from the genus Nostoc. Hornwort cells are monoplastidic, containing one large chloroplast in each cell. Simple pores allow for gas exchange (no guard cells, meaning pores are permanently open) Sporophyte Morphology:
