Cocconeis placentula var. euglypta Sexual reproduction of diatoms generating auxospores. Tomographical cross-sections through an auxospore from top to bottom. Chl = chloroplast, N = nucleus, UV = upper valve, LV = lower valve. Scale bar indicates 25 µm. Sample from a tropical freshwater aquarium. Sampling date 3/2021. The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Axioplan with Olympus OM-D M5 MKII.
