types of liverworts plants
Liverworts are primitive nonvascular plants, perhaps the most primitive true plants still in existence. There are two types. In thallose liverworts, the plant body (thallus) consists of flattened masses of cells that look leafy but show little differentiation into different cell types.oth types of liverworts are small, in the range of a few millimeters to a few centimeters, and easily overlooked. Some species, however, are conspicuous members of the forest-floor flora and may be much easier to find. One of these is Marchantia polymorpha. a thallose species.
Liverwort species may be either dioicous or monoicous. In dioicous liverworts, female and male sex organs are borne on different and separate gametophyte plants. In monoicous liverworts, the two kinds of reproductive structures are borne on different branches of the same plant.ome of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids.
1 Leafy liverworts have leaves. 2  Thalloid liverworts do not have leaves â they are sheets of cells. 3  If they are thick and have internal air spaces with pores to the outside, they are called complex thalloid liverworts. 4  If they are thin and have no air spaces or pores, they are called simple thalloid liverworts.ifferences between leafy liverworts and mosses. It is easy to confuse leafy liverworts with mosses. There are a number of ways to tell the difference between the two: 1  Liverwort leaves are lined up in straight rows, never have midribs, and are often lobed.
