Learning on ScreenVegetative Reproduction in the Alga ‘Stephanopyxis Turris’ ('Centrales’)
- Synopsis
- Shows the process by which the cells of the colony-forming ‘Stephanopyxis turris’ multiply vegetatively by binary fission. During interphase, the plastids double by simple fission. Cell division is initiated by longitudinal growth with migration of the nucleus to the equator of the cell. The central spindle appears during anaphase. The fission of the protoplast starts near the nucleus, and cell division is completed with the secretion of a new shell for each of the two daughter cells. Also shows the formation of resisting spores by ‘Stephanopyxis’.
