Diatom, SEM
Diatom. Coloured scanning electron micrograph (SEM) of the Arachnoidiscus 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: x250 when printed 10 cm wide

EDITORS COMMENTS
This print showcases the intricate beauty of a diatom, specifically the Arachnoidiscus sp. This single-celled algae belongs to a diverse group of photosynthetic organisms 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 part of the plankton at the base of food chains. What makes diatoms truly fascinating is their exquisitely patterned cell wall, called a frustule, resembling delicate glasswork. The frustule often exhibits rows of minuscule holes referred to as striae, adding another layer of intricacy to their structure. In this colored scanning electron micrograph (SEM), we can observe these remarkable features up close. With a magnification level of x250 when printed at 10 cm wide, this image allows us to appreciate the fine details that would otherwise go unnoticed by the naked eye. Its circular shape adds aesthetic appeal while highlighting its biological significance. Whether you are captivated by nature's wonders or have an interest in botany and biology, this stunning print serves as a reminder of the hidden marvels within our world's waters. It invites contemplation on both macro and micro scales – from phytoplankton thriving beneath ocean waves to individual diatoms shaping our aquatic environments.
