What is the name of the cell wall of diatoms? Short answer: The diatom cell wall is called a frustule, made from hydrated silica (silicon dioxide (quartz) + water → silicic acid (SiO 2 + 2 H 2 O → H 4 SiO 4 )), coated with a thin layer of polysaccharides. read more

Diatom cells are contained within a unique silica cell wall known as a frustule made up of two valves called thecae, that typically overlap one another. The biogenic silica composing the cell wall is synthesised intracellularly by the polymerisation of silicic acid monomers. read more

Diatoms have two shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) approach being bilaterally symmetric: this shape is the reason for the group name diatoms. A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule. read more

The "cell wall" of a diatom is the outer most portion, consisting of a cellular structure defined characteristically by a uniform almost stacking- like concentration. Like any ordinary multi cellular organism this so called "cell wall" coincidentally has without a doubt been discovered and consistently reaffirmed with any published literature pertaining to the field. read more
