The main difference between liverworts and mosses is that the gametophyte of liverworts is a thallose or a foliose whereas the gametophyte of mosses is a prostrate, branched filamentous structure. Thallose liverworts show less resemblance to mosses, they are not leafy at all but rather flat and ribbon like or hearts shaped and bilaterally symmetrical. These spores are released when the.

Furthermore, the plant body of ferns is differentiated into true leaves, stem, and roots. This growth form is due to their thin body parts and lack of vascular structures that would support upward growth.
