Figure 2

Schematic of a generic frustule (a) and of a centric diatom frustule (b) with cross-sectional profile of the valve. The inner layer with chambers called areolae is known as foramen. The roof of the areolae is called the cribrum, which contains a regular pattern of pores. The layer over the cribrum is a thin membrane known as cribellum, which is characterized by smaller pores.
