Scale bars indicate 25 µm.Three optical cross-sections through a fully developed auxospore.First:Top view showing chloroplasts.Second and third:The nucleus is visible.Fouth:The focal plane is on the hypovalae.Chl = chloroplast, N = nucleus, UV = upper valve, LV = lower valve.Please click on < or > on the image edges or on the dots at the bottom edge of the images to browse through the slides!Place name: Tropical freshwater aquarium   Latitude: 54.3018013     Longitude: 10.07120132Microscope Zeiss Axioplan, camera Olympus OM-D M5 MKII.

Scale bars indicate 25 µm.Three images. Two states of sexual reproduction generating auxospores.First:Early state (arrow).Second:Later phase of another couple (arrow). The epivalvae are opened, the cell plasmas have united. Optical cross section, the focal plane is near the hypovalvae.Third:Same phase. The focal plane is higher, the epivalvae become visible.UV = upper valve, LV = lower valve.Please click on < or > on the image edges or on the dots at the bottom edge of the images to browse through the slides!Place name: Tropical freshwater aquarium   Latitude: 54.3018013     Longitude: 10.07120132Microscope Zeiss Axioplan, camera Olympus OM-D M5 MKII.
