Diatoms – Definition, Structure, Life Cycle, Importance
A diatom is a tiny, single-celled algae with a hard shell made of silica, found in oceans, waterways, and soil. They play a crucial role in oxygen production, nutrient cycling, and the food web of aquatic ecosystems.

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.

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.

What are Diatoms?
Diatoms are widespread and can be found in almost all fresh and saline waters like brooks, rivers, lakes and sea. Even moist soil serves as a possible habitat. Some diatoms are floating, others live at the bottom of a body of water. Diatoms show an immense variety of shapes and structures.

Diatom cell size is restored via the formation and expansion of a special cell, the auxospore. The auxospore is usually a zygote. The basic shape of each diatom species is established during the expansion of the auxospore, but may be modified in subsequent mitotic cell divisions.
