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. Diatoms are among the most important and prolific microscopic sea organisms and serve directly or indirectly as food for many animals.

Diatoms are classified as eukaryotes, organisms with a membrane-bound cell nucleus, that separates them from the prokaryotes archaea and bacteria. Diatoms are a type of plankton called phytoplankton, the most common of the plankton types. Diatoms also grow attached to benthic substrates, floating debris, and on macrophytes.

Diatoms share with the bolidophytes a unique 2 amino-acid insertion in the large subunit of Rubisco. The characteristics of diatoms are that: all species are unicellular or colonial coccoid algae. None are free-living flagellates. the only flagellate cells produced are the male gametes (= sperm, spermatozoids) of 'centric' diatoms.

What is a diatom and why are they important? A diatom is a photosynthetic, single celled organism which means they manufacture their own food in the same way plants do. They are a major group of algae and form one of the most common forms of phytoplankton and join the myriad of organisms that drift on currents in the upper layers of the ocean ...

Diatoms Under the Microscope Classification and Characteristics What are Diatoms? Diatoms are photosynthetic organisms referred to as algae with a length/diameter of between 2 and 500 microns. They have a transparent cell wall (frustule) made of silicon dioxide, which is itself hydrated with a little amount of water.

Characteristics of diatoms. The main characteristics of diatoms are as follows: They have a cell wall that surrounds the entire cell as if it were an external skeleton. Their cell wall is formed by silica. They have little or no ability to move so they are carried away by different currents and surfaces.

Main Characteristics of Diatoms (Bacillariophyceae) The bacillariophyceae, popularly called diatoms, form a very important group of both fresh water and marine unicellular algae. There are about 16000 species of algae present in this group.The shape and size of these algae vary greatly. This may be in the form of boots, circles, triangles ...
