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.
Liverworts, like the species seen above, represent a branch of non-vascular plants, most of which are terrestrial. The name “liverworts” is derived from the belief in ancient times that the diseases of the liver could be cured with these plants.
Bryophytes is the informal group name for mosses, liverworts and hornworts. They are non-vascular plants, which means they have no roots or vascular tissue, but instead absorb water and nutrients from the air through their surface (e.g., their leaves).
Liverworts are a group of non-vascular plants similar to mosses. They are far different to most plants we generally think about because they do not produce seeds, flowers, fruit or wood, and even lack vascular tissue. Instead of seeds, liverworts produce spores for reproduction.
liverwort, (division Marchantiophyta), any of more than 9,000 species of small nonvascular spore-producing plants. Liverworts are distributed worldwide, though most commonly in the tropics.
Considered some of the most primitive of plants, liverworts consist of about 6,000 to 8,000 species. These non-vascular land plants lack stomata, specialized openings that regulate air flow in the plant.
Liverworts (Phylum Marchantiophyta) are very primitive, non-vascular land plants, persisting in very moist (but not aquatic) environments. Liverworts are flattened, ribbon-like leaves with a waxy cuticle, and are held to their substrate with single-celled rhizoids, or root-like structure
Liverworts are tiny nonvascular plants that have leaf-like, lobed, or ribbon-like photosynthetic tissues rather than leaves. Their rhizoids are very fine, they lack stems, and they are generally less than 10 centimeters (4 inches) tall.
Liverworts (Marchantiophyta) are currently classified as the plants most closely related to the ancestor of vascular plants that adapted to terrestrial environments. In fact, liverworts have colonized every terrestrial habitat on Earth and diversified to more than 7000 existing species (Figure 25.9).
Bryophytes are small, non-vascular plants that include three main groups: mosses, liverworts, and hornworts. They are among the earliest land plants and lack true vascular tissues like xylem and phloem, which are responsible for water and nutrient transport in higher plants.
