On the upper surface of the gametophytes of some thalloid liverworts, such as Marchantia, are specialized structures called gemma cups, which contain propagules called gemmae (Figure 3.11, 3.12B). Other leafy liverworts are more erect, with the three rows of leaves similar.

Other types of plant life in Antarctica Antarctica is home to an abundance of lichens, bryophytes, algae, and fungi. These organisms don’t have roots and consequently don’t require the complex intake of nutrients like other plants to survive.

In order to survive, the liverworts have adapted very well with the tundra biome. Just like all the other plants inhabiting tundra, they are well adapted to resist heavy winds and soil disturbances. Liverworts are also capable of continuing photosynthesis at low temperatures and low light intensities.

Liverworts are small, green, terrestrial plants. Liverworts do not have true roots, stems, or leaves. They have an above ground leaf-like structure named thallus and an underground structure known as a rhizoid. hope this helps you !

Although leafy liverworts look very much like mosses, they can be distinguished from mosses by their leaf arrangement. Leafy liverworts always have two lateral rows of leaves, and sometimes a row of leaves on the ventral side (bottom) of the stem, which are called underleaves.

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.

Rhizoid, a short, thin filament found in fungi and in certain plants and sponges that anchors the growing (vegetative) body of the organism to a substratum and that is capable of absorbing nutrients. In fungi, the rhizoid is found in the thallus and resembles a root.

Nonvascular Plants. Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15,000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).

The eggs are produced in tiny, typically somewhat flask-like structures called archegonia. Each archegonium holds one egg (in a swollen section called the venter) and the sperm enter through the channel in the narrower, tubular section (or neck).
