Planktonic diatom alga, SEM
Planktonic diatom alga. Coloured scanning electron micrograph (SEM) of a diatom alga. 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. The cell wall of a diatom is often intricately patterned, and has rows of tiny holes, known as striae

EDITORS COMMENTS
This print showcases the intricate beauty of a planktonic diatom alga, as captured through a scanning electron microscope (SEM). The vibrant colors and detailed structure of this microscopic organism are truly mesmerizing. Diatoms are unicellular algae that play a crucial role in our ecosystems as photosynthetic organisms. They can be found in both marine and freshwater environments, contributing to the rich diversity of life within these habitats. What sets diatoms apart is their cell wall, known as a frustule, which contains silica and exhibits remarkable patterns. In this image, we witness the delicate rows of tiny holes called striae adorning the cell wall. These minute details add to the overall allure of this diatom alga. The false coloring technique used enhances its visual appeal while maintaining scientific accuracy. The significance of this photograph extends beyond its aesthetic value; it serves as a reminder of nature's extraordinary complexity at even the smallest scales. By capturing such wonders through advanced microscopy techniques like SEM, scientists gain valuable insights into cellular structures and functions. Science Photo Library has once again provided us with an exquisite glimpse into the world around us – one that often goes unnoticed by our naked eyes but holds immense importance for our understanding of biology and ecology.
