diatoms are a microalgae group
Diatoms are algae, diatoms are protists. Diatoms are placed in the division Bacilliariophyta, which is distinguished by the presence of an inorganic cell wall composed of hydrated silica.
Diatoms are usually microscopic, but they can be 2mm in length. Marine diatoms are a yellowish brown colour.
