Diatom. Coloured scanning electron micrograph (SEM) of the wall of the diatom Thalassiosira sp.. Thalassiosira is an ocean diatom that is a major participant in the biological pumping of carbon to ocean depths and that has potential for mitigating global climate change. Diatoms are single-celled photosynthetic algae, of which there are about 100,000 species, that have mineralised cell walls (frustules) that contain silica and provide protection and support.
