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 ...
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. Bryophytes are characteristically limited in ...
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. This contrasts with the pattern in all vascular plants (seed plants and pteridophytes), where the diploid sporophyte generation ...
Marchantiales is an order of thallose liverworts (also known as "complex thalloid liverworts") that includes species like Marchantia polymorpha, a widespread plant often found beside rivers, and Lunularia cruciata, a common and often troublesome weed in moist, temperate gardens and greenhouses.
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.
Marchantia is a genus of liverworts in the family Marchantiaceae and the order Marchantiales. The thallus of Marchantia shows differentiation into two layers: an upper photosynthetic layer with a well-defined upper epidermis with pores and a lower storage layer. The thallus features tiny cup-like structures called gemma cups, containing gemmae ...
Conocephalum is a genus of complex thalloid liverworts in the order Marchantiales and is the only extant genus in the family Conocephalaceae. [ 1 ][ 2 ] Some species of Conocephalum are assigned to the Conocephalum conicum complex, which includes several cryptic species. [ 1 ]Conocephalum species are large liverworts with distinct patterns on ...
An antheridium is a haploid structure or organ producing and containing male gametes (called antherozoids or sperm). The plural form is antheridia, and a structure containing one or more antheridia is called an androecium. [1] Androecium is also the collective term for the stamens of flowering plants. Antheridia are present in the gametophyte ...
