The page not only provides Urdu meaning of Sporocarp but also gives extensive definition in English language. The three bryophyte clades (which may be treated as divisions) are the Marchantiophyta (liverworts), Bryophyta (mosses) and Anthocerotophyta (hornworts). Hornworts are a group of bryophytes (a group of non-vascular plants) constituting the division Anthocerotophyta (/ ˌ æ n θ oʊ ˌ s ɛ r ə ˈ t ɒ f ɪ t ə,-oʊ f aɪ t ə /).The common name refers to the elongated horn-like structure, which is the sporophyte.As in mosses and liverworts, the flattened, green plant body of a hornwort is the gametophyte plant. have been vaguely called liverworts, esp. The use of the "oicy" terminology refers to the gametophyte sexuality of bryophytes as distinct from the sporophyte sexuality of seed plants. [11] In bryophytes, the sporophytes are always unbranched and produce a single sporangium (spore producing capsule), but each gametophyte can give rise to several sporophytes at once. Regardless of their status, the name is convenient and remains in use as an informal collective term. Thus bryophytes disperse by a combination of swimming sperm and spores, in a manner similar to lycophytes, ferns and other cryptogams. [33] The bryophytes and vascular plants (embryophytes) also have embryonic development which is not seen in green algae. [19][21] Phylogenetic studies continue to produce conflicting results. The definition of Sporocarp is followed by practically usable example sentences which allow you to construct your own sentences based on it. All rights of the publication are reserved by What does liverwort mean? In hornworts, the meristem starts at the base where the foot ends, and the division of cells is pushing the sporophyte body upwards.

The thallus (body) of thallose liverworts resembles a lobed liver—hence the common name liverwort (“liver plant”). Updates? [14], Monoicous plants are necessarily hermaphroditic, meaning that the same plant has both sexes. Some extinct land plants, such as the horneophytes, are not bryophytes, but also are not vascular plants because, like bryophytes, they do not have true vascular tissue. liverwort - Student Encyclopedia (Ages 11 and up). In bryophytes, the sporophyte is a simple unbranched structure with a single spore-forming organ (sporangium). A number of physical features link bryophytes to both land plants and aquatic plants. The gametophyte generation consists of the haploid thallus and is the dominant generation; it develops from a germinating spore. These terms occasionally may be used instead of "monoicous" and "dioicous" to describe bryophyte gametophytes. Liverworts were formerly placed in the division Bryophyta with the mosses; however, phylogenetic evidence has led to a reorganization of their taxonomy. [6], Bryophytes exist in a wide variety of habitats. They consist of a stalk called a seta and a single sporangium or capsule. [14] All four patterns (autoicous, paroicous, synoicous and dioicous) occur in species of the moss genus Bryum. In liverworts the meristem is absent and the elongation of the sporophyte is caused almost exclusively by cell expansion. [1] They are characteristically limited in size and prefer moist habitats although they can survive in drier environments. [12], Liverworts, mosses and hornworts spend most of their lives as gametophytes. [34] When Phythium sphagnum is sprinkled on the soil of germinating seeds, it inhibits growth of "damping off fungus" which would otherwise kill young seedlings.

Gametophytes either “leafy” or dorsiventrally flattened (strap-shaped) and thalloid; leafy forms with leaves in 3 rows, 2 lateral and 1 below; leaves usually notched or lobed, with thickened midrib lacking; gametophytes with unicellular rhizoids; many chloroplasts per cell; sporophytes ephemeral, surrounded by gametophytic tissue,….
