Non-vascular plants are plants without a vascular system consisting of xylem and phloem. Instead, they may possess simpler tissues that have specialized functions for the internal transport of water. [citation needed] Non-vascular plants include two distantly related groups: Bryophytes, an informal group that taxonomists now [update] treat as ...
Hornwort. Phaeoceros laevis (L.) Prosk. see Classification. 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.
There are approximately 12,000 species. [2] Mosses are commonly confused with liverworts, hornworts and lichens. [7] Although often described as non-vascular plants, many mosses have advanced vascular systems. [8] [9] Like liverworts and hornworts, the haploid gametophyte generation of mosses is the dominant phase of the life cycle.
The Marchantiophyta (/ mɑːrˌkæntiˈɒfətə, - oʊˈfaɪtə / ⓘ) are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte -dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are ...
Bryophyte. Bryophytes (/ ˈbraɪ.əˌfaɪts /) [ 1 ] are a group of land plants (embryophytes), sometimes treated as a taxonomic division, that contains three groups of non-vascular land plants: the liverworts, hornworts, and mosses. [ 2 ] In the strict sense, the division Bryophyta consists of the mosses only.
Sphenophyllum was a slender climbing plant with whorls of leaves, which was probably related both to the calamites and the modern horsetails. Cordaites, a tall plant (6 to over 30 meters) with strap-like leaves, was related to the cycads and conifers; the catkin-like inflorescence, which bore yew-like berries, is called Cardiocarpus. These ...
The sporophyte remains small and dependent on the parent gametophyte for its entire brief life. All other living groups of land plants have a life cycle dominated by the diploid sporophyte generation. It is in the diploid sporophyte that vascular tissue develops. In some ways, the term "non-vascular" is a misnomer.
The glaucophytes, also known as glaucocystophytes or glaucocystids, are a small group of unicellular algae found in freshwater and moist terrestrial environments, [1][2] less common today than they were during the Proterozoic. [3] The stated number of species in the group varies from about 14 to 26. [4][5][6] Together with the red algae ...
