Diatoms are producers within the food chain. A unique feature of diatom cells is that they are enclosed within a cell wall made of silica (hydrated silicon dioxide) called a frustule. These frustules show a wide diversity in form, but are usually almost bilaterally symmetrical, hence the group name.
Best Answer: Diatoms are algae, and a part of phytoplankton (those tiny creatures in sea water that you can only see with a microscope). There are many types of diatoms, in various cool shapes! Check out http://en.wikipedia.org/wiki/Diatom Diatom cell walls consist of a unique silicate (silicon containing compound).When diatoms die, their remains (the hard cell walls) turn into a powdery like compound called diatomaceous earth.There are many uses of diatomaceous earth, including cat litter, filtration aid, insecticide, liquid absorbant, component of dynamite, and (not mentioned on the Wikipedia site!) slug repellent.here are many types of diatoms, in various cool shapes!
