filaments

Description:

Stephanopyxis (steff-ann-o-pick-sus) palmeriana, a filament-forming centric diatom in which the cells are linked together by processes arising from the valves. The valves are the parts of the shell or frustule at the ends of each cell, and are more sculpted than the girdle bands, and so refract more light appearing brighter in this image, which includes many resting cells. The golden colour from plastids which contain chlorophylls a and c, but more significantly with carotenoids such as fucoxanthin which provide the distinctive colour. Dark ground illumination.
