Place name: Pond near Großostheim (Germany)
Latitude: 49.88482168 Longitude: 9.09980822
Microscope Zeiss Axioplan, camera Olympus OM-D M5 MKII.
Sampling date 04/2021. Scale bars indicate 25 µm.
Three images.
| First: | Synoptic representation of the test (shell). Cell in lateral view. |
| Second to fourth: | Optical cross-sections, the last one shows the large nucleus with one nucleolus at position nine o’clock. |
| Fouth: | Region of the test´s neck with a large quartz grain, which is covered with silica produced by the amoeba. |
| Fifth: | A look inside the test shows that idiosomes are produced in reserve and stored in the cytoplasm in order to be used during cell division to build the test of the daughter cell. |
