diátómák

Diátómák, also known as diatoms, are a group of single-celled algae that belong to the class Bacillariophyceae. They are characterized by their unique cell walls, which are composed of silica and are intricately patterned with intricate designs. These patterns are often used for identification and classification purposes. Diatoms are found in both freshwater and marine environments, and they play a significant role in the food chain as a primary producer. They are also important in the global carbon cycle, as they absorb and store carbon dioxide during photosynthesis. Diatoms have been used in various applications, including water quality testing, as they can indicate the presence of pollutants, and in the production of diatomaceous earth, a natural abrasive. They are also used in the field of nanotechnology for their unique properties. Diatoms have a long fossil record, dating back to the Jurassic period, and they continue to be a subject of scientific study due to their diversity and ecological importance.
