Diatom, SEM
Diatom. Coloured scanning electron micrograph (SEM) of a Triceratium morlandii diatom. Diatoms are single-celled photosynthetic algae, of which there are about 100, 000 species. They have mineralised cell walls (frustules) that contain silica and provide protection and support. The diatoms form an important part of the plankton at the base of the marine and freshwater food chains

EDITORS COMMENTS
This print showcases the intricate beauty of a Triceratium morlandii diatom, captured using a scanning electron microscope (SEM). Diatoms are remarkable single-celled algae that play a vital role in our ecosystems. With around 100,000 different species, they form an essential part of the plankton at the foundation of both marine and freshwater food chains. The image reveals the diatom's mineralized cell walls, known as frustules, which provide crucial protection and support. Composed primarily of silica, these structures not only safeguard the delicate organism but also contribute to its unique shape and design. In this false-colored SEM image, we witness nature's mastery in creating such specialized biological systems. The vibrant hues highlight various features within the diatom's structure while adding an artistic touch to this scientific marvel. As we delve into this microscopic world, we gain insight into the wonders hidden beneath our waters. These unicellular organisms serve as phytoplankton – tiny plants that harness sunlight through photosynthesis – sustaining countless other aquatic life forms. Through this mesmerizing photograph from Science Photo Library, we are reminded of nature's complexity and resilience. It is a testament to how even seemingly insignificant organisms can have profound impacts on our planet's biodiversity and overall health.
