Place name: Moor called Schwemm near Walchsee (Tyrol, Austria)
Latitude: 47.657707 Longitude: 12.299540 Elevation: 669 m
Microscope Zeiss Axioplan, camera Olympus OM-D M5 MKII. DOF images.
Sampling date 06/2023. Scale bars indicate 25 µm (1, 3–5), 10 µm (2).
Five images.
| First and third: | Synoptic representation of the upper cell wall. Inset: Higher magnification of the pores in the cell wall through which the protective mucus is secreted. |
| Second: | Optical cross-section through the chloroplasts showing parts of the lobed chloroplast and storage substances (oleosomes and crystals). |
| Fourth: | The optical cross section through the cell shows parts of the lobed chloroplast and storage substances (crystals). |
| Fifth: | The optical cross section through the cell shows pyrenoids and storage substances (crystals). In the pyrenoids, the cell produces the storage substance starch, which is deposited as a shell around them, which can be clearly seen here. |
