When these organisms reproduce, they form a thin structure called the protonema.
When these organisms reproduce, they form a thin structure called the protonema. These organisms can be divided into two groups, one of which contains the antheridia and archegonia on the same body and are referred to as monoicous. Throughout most of their life cycle these organisms exist as a haploid gametophyte while during reproduction, the sporangium is encased in a stalk called a seta. This group, which includes genus Marchantia, contrasts with tracheophytes in their lack of xylem and phloem. For 10 points, name this group of land plants that are non vascular and non flowering and include liverworts and mosses.
