Moss is found on mats on moist ground, tree trunks or on rocks. Mosses have several characteristics that tell them apart from other bryophytes. Only mosses have a multicellular rhizoid, a root-like subterranean tissue that absorbs water and nutrients from the soil. Liverworts are found in treeless plains especially in the artic. Liverworts and hornworts have single celled rhizoids. Hornworts may be found world-wide, though they tend to grow only in places that are damp or humid. Hornworts and liverworts are unique bryophytes in that they have stomata; cells specialized for photosynthetic gas exchange, on their sporophytes. Liverwort sporophytes lack stomata. In addition mosses do not have true leaves or stems. Their leaf-like structures are called phyllids. They are typically only one cell thick, although phyllids in some species are several cells thick.
Liverwort: Liverwort is a non-vascular plant. Most liverworts are small, usually from 2–20 millimeters wide with individual plants less than four inches long, so they are often overlooked. Liverworts produce flattened stems with overlapping scales or leaves. They are distributed globally in almost every available habitat, most often in humid locations although there are desert and arctic species as well. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Liverworts have a gametophyte-dominant life cycle, with the sporophyte dependent on the gametophyte.
Hornwort: Hornwort is a non-vascular plant. Hornworts may be found world-wide, though they tend to grow only in places that are damp or humid. Some species grow in large numbers as tiny weeds in the soil of gardens and cultivated fields. Hornworts are usually five centimeters in diameter.
Moss: Moss is a non-vascular plant. Mosses are small, soft plants that are typically 1–10 cm tall, though some species are much larger. They commonly grow close together in clumps or mats in damp or shady locations. They do not have flowers or seeds, and their simple leaves cover the thin wiry stems. By contrast to other plants, mosses and other bryophytes have only a single set of chromosomes.
Liverwort: (usually found in moist locations)Liverwort is a non-vascular plant, found under the classification of the Bryophyte family. They have no true roots, stems and leaves, but have and above ground leaf-like structure called the thallus. They also have underground structure called the rhizoid. Their rhizoids are one celled.
Hornwort: (temperate and tropical regions on tree trunks, riverbanks, and other damp locations) Hornwort is a non-vascular plant, also found under the Bryophyte family. Like moss, hornwort have stomata’s, or cells that are used in the gas exchange in photosynthesis. Unlike moss, the spaces between the cells are filled with mucilage, a type of water absorbing material. Their rhizoids are also one celled.
Moss: (usually found in moist locations) Mosses can also be found under the Bryophyte family. However, they have multi-celled rhizoids. Like hornwort, mosses contain stomata that help with photosynthesis. Only true to mosses though, is that they have radial symmetry, which means they can be cut down the middle and be similar on both halves. They also have no true leaves or stems. The structure found on them is known as Phyllids.
As you can see, these three non-vascular plants share things and common and are different. All of them must reproduce by using sperm and egg, so they are NOT asexual. Each of these need female and male plants in order to reproduce.
Moss, liverwort, and hornwort are all nonvascular plants. All nonvascular plants lack true stems, true leaves, and true roots. They hold themselves to the ground by a thin like structure called rhizoid. Contrasting against themselves There are 10,000 different kinds of moss but liverwort and hornwort only have a few. Liverwort and hornwort are different then moss because the rhizoid of moss has many cells but the others are just one long cell. Contrasting against other plants Nonvascular plants are different from vascular plants because they lack true stems, leaves, and roots. The only thing that holds them into the ground is a rhizoid. The rhizoid just holds the plant in place. That is the main difference between the two.
The ancients thought that liverwort could cure diseases to the liver. Some common gameotphyts have flattened gametophytes with lobes resembling those of liver the combination “liverwort.” Although the lobed liverworts are the best-known representatives of this phylum, they constitute only about 20% of the species
Mosses
The gametophytes of mosses typically consist of small leaflike structures (not true leaves which contain vascular tissue) arranged spirally or alternately around a stemlike axis (figure 37.4); the axis is anchored to its substrate by means of rhizoids.
Hornwort
The small hornwort sporophytes resemble tiny green broom handles rising from filmy gametophytes usually less than 2 centimeters in diameter. The sporophyte base is embedded in gametophyte tissue, from which it derives some of its nutrition. However, the sporophyte has stomata, is photosynthetic, and provides much of the energy needed for growth and reproduction. Hornwort cells usually have a single chloroplast.
a sporophyte is a stage in a plants life cycl that produces spores. A gametophyte is a stage in a plants life cycle that produces gametes. A rhizoid is a thinlike structure that anchors some simple plants.
Liverwort, moss, and hornwort are alike vascular plants because there color, they can also produce sexually and asexually. The differences are vascular plants have tissues which transport water, minerals and photosynthetic materials throughout the plant’s roots, stems, and leaves. Non-vascular plants can't do these things. Vascular plant makeup the majority of plants on earth today. Also non-vascular plants don’t have stems roots or leaves vascular plants do. Vascular plants are able to grow to a larger size than nonvascular plants, which lack woody tissue that is needed to provide support for larger growth. Nonvascular plants naturally grow to around 1-2 centimeters, while vascular plants can grow many feet high. Non vascular plants are also more commonly found in damp and shady areas, since they do not have vascular tissue to hydrate their bodies. Instead, they must absorb water on their surface, making it difficult to survive for long periods in dry areas. Vascular plants, however, can survive in most any climate as long as their basic needs for water, sunlight, and appropriate temperatures are met. There are more such as there are more types of vascular plants then there are non-vascular. These are the differences and common thing these type of plant have in common. Nonvascular-In these groups, the primary plants are the haploid gametophytes, with the only diploid portion being the attached sporophyte, consisting of a stalk and sporangium. Vascular-Only the germ cells and gametophytes are haploid. By contrast, the principal generation phase in non-vascular plants is usually the gametophyte, which is haploid with one set of chromosomes per cell. In these plants, generally only the spore stalk and capsule are diploid.
