Diatom - Wikipedia A diatom (Neo-Latin diatoma) [a] is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world Living diatoms make up a significant portion of Earth's biomass
Diatom | Description, Characteristics, Reproduction | Britannica diatom, (class Bacillariophyceae), any member of the algal class Bacillariophyceae (division Chromophyta), with about 16,000 species found in sediments or attached to solid substances in all the waters of Earth
What are Diatoms? - Diatoms of North America Diatoms are the most diverse protists on earth Diatoms are eukaryotes, one of the Heterokont algae Estimates of the number of diatom species range from 20,000 - 2 million Scientists are discovering new species every year
Diatom Species: What They Are Why They Matter Diatoms are microscopic, single-celled algae found in nearly every aquatic environment on Earth, from oceans and freshwater lakes to moist soils These abundant organisms, often overlooked due to their small size, are a foundational component of many ecosystems
Diatom morphology and adaptation: Current progress and potentials for . . . Diatoms are a major phytoplankton group, playing a critical role in the biogeochemical cycles of chemical elements such as carbon They are one of the most abundant single-celled photosynthetic algae, contributing to about 40% of total marine primary production
DiatomBase Diatoms are found in marine, estuarine and freshwater ecosystems, inhabiting a wide range of environmental conditions Because they are found in almost any place that has, or has had, water, and due to their efficient photosynthetic processes, they are important players in the global cycling of carbon and oxygen
Diatoms - Jewels of the Sea | MarineBio Conservation Society Diatoms are unicellular organisms within the phylum Bacillariophyta, characterized by a bipartite silica shell called a frustule They possess chloroplasts containing chlorophylls a and c, enabling oxygenic photosynthesis akin to higher plants
Diatoms: Small Sized but Big Impacts - ArcGIS StoryMaps Diatoms are single celled organisms, they are very small algae of the class Bacillariophyceae (Bhat et al , 2025) Diatoms are found primarily in oceans and freshwater environments around the world
