A frustule is the hard and porous cell wall or external layer of diatoms. The frustule is composed almost purely of silica, made from silicic acid, and...

Like other diatoms, Gyrosigma has a siliceous cell wall called a frustule. The frustule is composed of two sections called valves, with one valve fitting...

Silicates (glass) are common in marine biominerals, where diatoms form frustules and radiolaria form capsules from hydrated amorphous silica (opal). The...

Tabellaria is a genus of freshwater diatoms. They are cuboid in shape, and the frustules (siliceous cell walls) are attached at the corners so that the colonies...
