Biddulphiophycidae

O. sinensis is closely related to O. mobiliensis and O. regia but the processes are nearly parallel to the cell axis and the processes are close to the processes. The valve face between the processes is flat or concave.

Phasde contrast micrograph of living diatom - cracked.

Eucampia (you-camp-ee-a) zoodiacus is a filament forming diatom (stramenochrome). Adjacent cells are attached by two interlocking apical elevations. Differential interference microscopy. data on this strain.

Chain forming diatom, which produces wing like extensions one valve end, which link adjacent cells. This is a cosmopolitan species.

Depth-of-focus image exhibiting structure of the frustules. Chloroplasts are concentrated in cell centers due to long lasting exposition with microscope's illumination. Scale bar indicates 25 m. The image was built up using several photomicrographic frames with manual stacking technique. Sample from North Sea near Heligoland (spring diatom bloom). Images were taken using Zeiss Universal with Olympus C7070 CCD camera.For more look at www.protisten.de/english/gallery_main/gallery_main.htmlFor high-resolution images please ask postmaster@protisten.de.
