| German | German Kieselalge. Kettenförmige Kolonien; Bildung von Dauersporen: erste Differenzierungsteilung (äqual), zweite Differenzierungsteilung (extrem inäqual, Polarisierung des Zellinhalts infolge des Streckungswachstums), Keimung der Dauersporen. Mit Zeitraffung. |
| English | English Stephanopyxis is capable of interrupting its vegetative reproduction by the formation of resting spores. The resting spores are formed in pairs via two differentiating cell divisions. The first division is equal, the second, however, extremely unequal, since during growth in the longitudinal direction the cell contents are polarized. Resting spores germinate by beginning with normal vegetative cell divisions. The walls of the spores are not shed but passed along from division to division. |
