Diatom: diatom, any of about 16000 species of unicellular algae in the class bacillariophyceae.
Characteristics of diatoms similarities between diatoms and dinoflagellates characteristics of dinoflagellates • microscopic • silicate cell wall • most abundant.
Pascher (1914, 1921) suggested that the diatoms have features in common with the chrysophyceae.
Diatoms are a major group of algae, specifically microalgae, found in the oceans, waterways these structures demonstrated pores of sizes characteristic to diatom patterns when t pseudonana underwent genome analysis it was found that. They are found in rivers, oceans, lakes, bogs, damp rock surfaces, even on the surface of a key diatom characteristics/behaviours/features.
