What makes liverwort unique?
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. The plants get their name from the resemblance to the shape of the liver found in its leaves.
What is a liverwort in biology?
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. Leafy liverworts are the simplest species and have just a single layer of cells in their leaves.

What is Thalli liverwort?
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. The thallus (body) of thallose liverworts resembles a lobed liver—hence the common name liverwort (“liver plant”).
What are some characteristics of hornworts?
Like all bryophytes, hornworts lack vascular tissue (xylem and phloem), and therefore do not have true roots, stems, or leaves. The hornwort plant body typically consists of a flattened, somewhat lobulated structure called a thallus, which is usually less than 0.8–1.6 inches (2 centimeters) in diameter.
What do liverwort Gametangia look like?
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 is the difference between hornworts and liverworts?
The main difference between liverworts and hornworts is that the liverworts contain lobate, green, leaf-like structures whereas the hornworts contain narrow, pipe-like structures. Furthermore, the sporophyte of liverworts is short and small while the sporophyte of hornworts is long and slender.
Where can liverworts be found?
Liverworts are distributed worldwide, though most commonly in the tropics. Thallose liverworts, which are branching and ribbonlike, grow commonly on moist soil or damp rocks, while leafy liverworts are found in similar habitats as well as on tree trunks in damp woods.
What is common liverwort used for?

How did the liverworts change the early World?
The emergence of the embryophytes, or land plants, greatly changed the atmosphere of the early world. The atmosphere was composed heavily of carbon dioxide, and contained little oxygen. As plants like ancient liverworts began to emerge, they consumed the carbon dioxide and released oxygen.
