Diatoms. The cell walls of diatoms are made of silica formed into their characteristic pillbox shape. Diatoms are composed of two valves or frustules, one on top of the other, within which the living matter of the diatom is found.
Diatom cells are contained within a unique silica cell wall comprising two separate valves (or shells). The biogenic silica that the cell wall is composed of is synthesised intracellularly by the polymerisation of silicic acid monomers.This material is then extruded to the cell exterior and added to the wall.iatoms are a major group of algae, and are among the most common types of phytoplankton. Diatoms are unicellular, although they can form colonies in the shape of filaments or ribbons (e.g. Fragilaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stars (e.g. Asterionella).
