Therefore, diatoms are simply aquatic organisms, which can be found in such environments as fresh and marine . After a bloom, many diatoms die and are left un-decomposed on the ocean floor which removes their carbon from the carbon cycle. Characteristics of Diatoms 3. 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. diatom, paramecium Fungi Eukaryote Mostly Multicellular (Many-celled) Breaks down or absorbs materials from dead or decaying The organisms which are placed under the kingdom Animalia are heterotrophic and depend on the other organisms for food. The organisms which are placed under the kingdom Animalia are heterotrophic and depend on the other organisms for food. Diatoms are thought to have evolved and come into being during the Triassic Period, and the best fossil records are from the early Jurassic period.

The opinion over classification of heterokonts that include algae, kelp, and diatoms is still debated.They can be either considered as a phylum, or kingdom, or some where between. Classification. Classification of Bacillariophyta 3. Diatoms belong to a large group called the heterokonts, which include both autotrophs such as golden algae and kelp; and heterotrophs such as water moulds.The classification of heterokonts is still unsettled: they may be designated a division, phylum, kingdom, or something intermediate to those.Consequently, diatoms are ranked anywhere from a class, usually called Diatomophyceae or .

The classification of heterokonts is still unsettled, and they may be treated as a division (or phylum), kingdom, or something in-between. This female gamete is known as an egg. Thallus is unicellular, uninucleate diploid and show radial or bilateral symmetry. Diatoms commonly found in the marine plankton may be divided into the centric diatoms including three sub-orders based primarily on the shape of the cells, the polarity and the arrangement of the processes. The five kingdom classification are- Monera, Protista, Fungi, Plantae and Animalia.

Diatoms belong to a large group called the heterokonts, which include both autotrophs such as golden algae and kelp; and heterotrophs such as water moulds.The classification of heterokonts is still unsettled: they may be designated a division, phylum, kingdom, or something intermediate to those.Consequently, diatoms are ranked anywhere from a class, usually called Diatomophyceae or . Diatom (Neo-Latin diatoma) refers to 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 the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from . Classification. 2. Cell Structure 7. The scientific name of the diatom is Chrysophyta. Reproduction 8. who are they grouped with). Nevertheless, diatoms belong to the Kingdom Protista, the Division (or Phylum) Chrysophyta, and the Class Bacillariophyceae. Diatoms are photosynthetic organisms referred to as algae with a length/diameter of between 2 and 500 microns. Consequently, diatoms may be arranged anywhere from class (Bacillariophyceae) to a phylum (Bacillariophyta).Diatoms are also sometimes called Class Diatomophyceae. Plant Body 6. Consequently, diatoms may be arranged anywhere from class (Bacillariophyceae) to a phylum (Bacillariophyta).Diatoms are also sometimes called Class Diatomophyceae. 3. Features of Bacillariophyta: The Bacillariophyta, commonly known as the diatoms, are ubiquitous algae of both fresh- and salt-water and of damp places including aerial habitats as, old walls, rocky cliffs, bark of trees, and damp soils. Members are commonly known as diatoms and are commonly found in fresh water, water, in air or on soil. They further belong to the super group Chromalveolata and are grouped into the Strameopiles as the lineage Diatoms. Description of Diatoms 2. These are eukaryotic organisms with well-developed organelles. These sediments are mined to use as a filtering medium and can be found in products like paints and toothpastes.
