Diatom shell, SEM
Diatom shell. Coloured scanning electron micrograph (SEM) of the shell of a Biddulphia sp. diatom. The diatoms are a group of photosynthetic, single-celled algae containing about 10, 000 species. They form an important part of the plankton at the base of the marine and freshwater food chains. The characteristic feature of diatoms is their intricately patterned, glass-like cell wall, or frustule. The frustule often has rows of tiny holes, known as striae. Magnification: x1300 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a diatom shell, captured using a scanning electron microscope (SEM). The image reveals the stunningly detailed structure of a Biddulphia sp. diatom, one of approximately 10,000 species belonging to this group of single-celled algae. Diatoms play a vital role in marine and freshwater ecosystems as they form an essential part of the plankton at the base of food chains. Their glass-like cell walls, known as frustules, are their distinguishing feature. These frustules exhibit mesmerizing patterns and often contain rows of minuscule holes called striae. At a magnification level of x1300 when printed at 10 centimeters wide, this photograph allows us to appreciate the microscopic wonders that exist within our natural world. The false coloring applied to enhance visual contrast adds an artistic touch while maintaining scientific accuracy. Steve Gschmeissner's skillful capture invites viewers into the realm of botany and biology by showcasing the delicate beauty hidden within these unicellular organisms. This image serves as a reminder that even on such small scales, nature is capable of producing breathtaking artistry.
