Against such a simple interpretation, Celakovsky classified the production of a leafy gametophore from a moss protonema as an alternation of homologous shoots.
The protonemal stages exhibit tip growth and an axially oriented system of microtubules, whereas the three dimensional gametophores exhibit growth from an apical cell/meristem and have cells with hooplike cortical arrays and PPBs prior to mitotic cell division (Doonan et al., 1987; Doonan & Duckett, 1988).
The length and width of gametophores, as well as the diameter of the gametangia were clearly different for both species.
