Moss spores germinate to form an alga-like filamentous structure called the protonema. ... These give rise to gametophores, stems and leaf like structures. Bryophytes do not have true leaves (megaphyll. Protonemata are characteristic of all mosses and some liverworts but are absent from hornworts.

Is the protonema part of the gametophyte or Sporophyte generation?

The gametophyte refers to all organs and tissues that are a part of the haploid generation. There are two different developmental stages of the gametophyte: the protonema, and the gametophore. The protonema is the first part of the moss that develops from the germinating spore.

What is protonema where it is found?

The protonema, which grows directly from the germinating spore, is in most mosses an extensive, branched system of multicellular filaments that are rich in chlorophyll. This stage initiates the accumulation of hormones that influence the further growth of newly formed cells.
