A frustule is the hard and porous cell wall or external layer of diatoms.

The meaning of FRUSTULE is the 2-valved siliceous shell of a diatom.

The frustules, or cell walls, of diatoms are made of opaline silica and contain many fine pores. Large quantities of frustules are deposited in some ocean and lake sediments, and their fossilized remains are called diatomite. Diatomite contains approximately 3,000 diatom frustules per cubic millimetre (50… Read More

Frustules are the hard and porous cell walls of diatoms, a type of algae. They are primarily composed of silica and exhibit intricate and species-specific patterns.

Jul 15, 2021 · Imaging of diatoms applying visible light, electron and X-ray microscopy provide a deeper insight into the morphology of their frustules.

A frustule is the external, siliceous part of the diatom cell wall. In Latin frustule means a little piece. The frustule is composed of two valves and the copulae, or girdle bands. One valve, or theca, is slightly larger than the other valve. The two valves overlap one another in a manner similar to the halves of a pill box, or a Petri dish.

The frustules, made of a composite of organic material and silica that is often intricately and ornately shaped, are not as stiff as calcite but are more flexible (Hildebrand, 2008).

May 1, 2023 · Diatoms are the most important contributors to marine primary production, and their most distinctive feature is the silicified cell wall, known as frustule.

May 12, 2022 · Here, we explain the general architectures of frustules and describe the main cellular events and key steps in their morphogenesis. The name diatom originates from the Greek word diatomos, which means “two parts,” indicating that each frustule is composed of two pieces, which together fully encase the protoplast.
