Diatom frustule, SEM
Diatom frustule. Coloured scanning electron micrograph (SEM) of the frustule of a Pinnularia 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: x2000 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a Diatom frustule, captured using a scanning electron microscope (SEM). The image reveals the glass-like cell wall, or frustule, of a Pinnularia sp. diatom. These single-celled algae are part of the vast group known as diatoms, which encompass approximately 10,000 different species. Diatoms play a crucial role in marine and freshwater ecosystems as they form an essential component of plankton at the base of food chains. Their photosynthetic abilities contribute to oxygen production and carbon dioxide absorption in aquatic environments. What sets diatoms apart is their remarkable frustule pattern, resembling delicate artwork with rows of minuscule holes called striae. This false-colored SEM image allows us to appreciate the intricacy and complexity that nature has bestowed upon these unicellular organisms. With a magnification level of x2000 when printed at 10 centimeters wide, this photograph by Steve Gschmeissner from Science Photo Library offers viewers an up-close glimpse into the microscopic world within our waters. It serves as a reminder that even within seemingly invisible realms lies astonishing beauty waiting to be discovered by those who dare to explore it through scientific lenses.
