What are the characteristics of Hepatophyta?
What are the characteristics of Hepatophyta?
They are the simplest of the plants with leaflike structures. Their leaves lack vascular tissue, each is deeply cleft so as to appear two-lobed, and they are arranged in two rows along a much branched stem. Unlike the true mosses, which typically appear somewhat erect, leafy liverworts form small, flat mats.
What is phylum Hepatophyta?
Hepatophyta A phylum comprising the liverworts – simple plants that lack vascular tissue and possess rudimentary rootlike organs (rhizoids). Liverworts occur in moist situations (including fresh water) and as epiphytes on other plants.

What are the characteristics of Tracheophyta?
They are covered with a waxy layer, or cuticle that holds in water. They also have stomata, or pores that help them take in and let out gasses like carbon dioxide and oxygen. Their roots take up water and nutrients from the soil and anchor them to the soil.
What are the main characteristics of bryophytes?
The defining features of bryophytes are:
- Their life cycles are dominated by a multicellular gametophyte stage.
- Their sporophytes are unbranched.
- They do not have a true vascular tissue containing lignin (although some have specialized tissues for the transport of water)

What is the life cycle of Hepatophyta?
Aside from lacking a vascular system, liverworts have a gametophyte-dominant life cycle, i.e. the plant’s cells are haploid for most of its life cycle. Sporophytes (i.e. the diploid body) are short-lived and dependent on the gametophyte. This is in contrast to the pattern exibited by most higher plants and animals.
What are the characteristics of liverworts?
Liverworts are small, green, terrestrial plants. They do not have true roots, stems, or leaves. Instead, they have an above ground leaf-like structure, known as a thallus, and an underground structure, known as a rhizoid.
Is marchantia an example of liverwort?
Common liverwort Marchantia berteroana Marchantia/Lower classifications
Marchantia polymorpha, sometimes known as the common liverwort or umbrella liverwort, is a large liverwort with a wide distribution around the world. It is variable in appearance and has several subspecies. It is dioicous, having separate male and female plants.

What are the characteristics of Anthocerophyta?
The Anthocerotophyta are characterized by their long, horn-shaped sporophyte, from which they get their name “hornworts”. Although the sporophyte remains attached to its parent, like in other bryophytes, it differs significantly in that it possesses an meristematic region at its base.
What is the classification of a Hepatophyta?
Hepatophyta. Hepatophyta (liverworts) A division of plants, formerly ranked as the class Hepaticae, characterized by a combination of features. The capsule is usually ovoid or spherical and does not have a lid; when ripe, it usually splits into 4 ‘valves’ to release the spores. A tubular perianth often surrounds the developing capsule.
Are liverworts bryophytes?
Liverworts (phylum Hepatophyta) are one of three ancient lines of bryophytes (liverworts, hornworts, and mosses): low-growing land plants that depend on free water (rain) for fertilization. Liverworts, with about six thousand species, generally prefer somewhat cooler, moister, shadier, and more acidic habitats than mosses.
What is the dominant gametophyte in liverwort?
Like any bryophyte, a liverwort has a dominant (conspicuous) green gametophyte and a small, attached sporophyte, which is a single-stalked sporangium that developed from a fertilized egg. As in hornworts, liverwort gametophytes are typically dorsiventrally symmetrical (flattened).
What type of plant is hepatica?
hepatica (hĬpăt´Ĭkə) or liverleaf, any plant of the genus Hepatica of the family Ranunculaceae (buttercup family), low, woodland, spring wildflowers of the north temperate zone, popular for wild gardens.
