Diatom cell wall, SEM
Diatom cell wall. Coloured scanning electron micrograph (SEM) of the pattern of small holes, called striae, in the cell wall of a diatom alga. This is a Coscinodiscus sp. diatom. A diatom is a planktonic unicellular alga that has silica in its cell wall (frustule). Diatoms are photosynthetic, and they are found in both marine and freshwater environments

EDITORS COMMENTS
This print showcases the intricate beauty of a diatom cell wall, captured using a scanning electron microscope (SEM). The image reveals an array of small holes known as striae, forming an exquisite pattern within the cell wall of a Coscinodiscus sp. diatom alga. Diatoms are unicellular algae that thrive in both marine and freshwater environments, playing a vital role as photosynthetic organisms. The uniqueness of this photograph lies in its ability to unveil the hidden world of microscopic life. The false-colored SEM image allows us to appreciate the delicate structures and remarkable complexity present even at such minuscule scales. Silica, found abundantly in these diatoms' frustules or cell walls, adds strength and rigidity to their structure. With its fusion of artistry and scientific exploration, this image serves as a testament to nature's creativity and diversity. It reminds us that beneath our feet lie countless wonders waiting to be discovered. Whether you are fascinated by patterns or have an interest in biology or zoology, this photograph offers a glimpse into the mesmerizing realm of phytoplankton. Science Photo Library has masterfully captured the essence of this diatom's cell wall through their expertise in scientific imaging. This particular print is not associated with any commercial use but rather seeks to inspire awe for our natural world and encourage further exploration into its mysteries.
