| Stentor roeselii; stage of division (1): the two oral areas with the adoral membranella zones (AZM1 and AZM 2) are recognizable. AZM2 belongs to the newly formed oral area. The white triangles mark the ribbon-shaped macronucleus that runs through the entire cell. The left daughter with AZM1 is called proter, the right, newly formed daughter is called opisthe.
