What is a Diatom? A diatom is a photosynthetic, single celled organism which means they manufacture their own food in the same way plants do. They are a major group of algae and form one of the most common forms of phytoplankton and join the myriad of organisms that drift on currents in the upper layers of the ocean and lakes.

- There are two types of plankton: tiny plants--called phytoplankton, and weak-swimming animals--called zooplankton. Some are babies that will grow into strong-swimming, non-planktonic adults. Others will remain plankton for their entire lives.hey are single-celled yellow algae whose cell walls contain a lot of silica, glass-like substance. The actual diatom fits inside this cell wall, with one half of the wall fitting over the second half, like a lid. The name diatom actually means cut in two in Greek.

Diatom 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.iatoms are producers within the food chain.

Diatomaceous earth A sample of food-grade diatomaceous earth. Diatomaceous earth /ˌdaɪ.ətəˌmeɪʃəs ˈɜrθ/ , also known as D.E. , diatomite, or kieselgur / kieselguhr, is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder.he typical chemical composition of oven-dried diatomaceous earth is 80 to 90% silica, with 2 to 4% alumina (attributed mostly to clay minerals) and 0.5 to 2% iron oxide. Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae.

Diatom 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. The symmetry is not perfect since one of the valves is slightly larger than the other, allowing one valve to fit inside the edge of the other.

Introduction The high production of lipids in many diatom species has created great interest in diatoms as a source of biofuels. Indeed, as one of the important global sources of carbon fixation, diatoms already are an important biofuel for aquatic food webs. It is estimated that the photosynthetic activity of diatoms produces between 20 and 40% of the earth’s oxygen (0 2).

Diatomic molecule Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements. The prefix di-is of Greek origin, meaning two. If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H 2) or oxygen (O 2), then it is said to be homonuclear.he only chemical elements that form stable homonuclear diatomic molecules at standard temperature and pressure (STP) (or typical laboratory conditions of 1 bar and 25 °C) are the gases hydrogen (H 2), nitrogen (N 2), oxygen (O 2), fluorine (F 2), and chlorine (Cl 2).

- Diatoms are a type of protist, a microscopic organism. What makes diatoms remarkable is they have shells made from organic compounds and silica. These shells are left behind when a diatom dies.Diatomaceous earth is a mineral that is formed from fossilized diatom shells, and this is mined for a number of industrial purposes.The product of diatoms, diatomaceous earth, is typically used, though living diatoms are also useful.iatoms are often used to filter water, particularly water in hot tubs and swimming pools. However, a vast variety of fluids can be filtered with diatoms, including different syrups, alcoholic beverages, medicines, solvents and other chemicals.

Diatom Diatoms have some practical uses. Diatom communities are a popular tool for monitoring environmental conditions, past and present. They are commonly used in studies of water quality. They are also of interest to nanotechnology.iatoms (Greek: dia = through + temnein = to cut: cut through) are a big group of eukaryotic algae. They are one of the most common types of phyto plankton.

- Diatoms are single-celled algae that form a silica-based cell wall. They are broken up into two major groups, the centric diatoms and the pennate diatoms, based on the form of their frustule.

Customer Loyalty in Retail Banking: Global Edition 2013 For many bankers, the link between loyalty and financial results is somewhat unclear. This year’s report, based on Bain’s proprietary research with 190,200 consumers in 27 countries, sheds light on how banks are using (or failing to use) loyalty to improve the economics of the business.

What Does the Diatom Do in the Ecosystem? Since humans and all other animals need oxygen to breathe, we all rely indirectly on diatoms to sustain us. By fixing carbon or converting it from carbon dioxide into sugar, diatoms also reduce the amount of carbon dioxide in the atmosphere just as terrestrial plants do. Food. In the ocean, diatoms are eaten by tiny animals called zooplankton.

Diatom Diatoms belong to a large group called the heterokonts, including both autotrophs (e.g. , golden algae, kelp) and heterotrophs (e.g. , water moulds). Their yellowish-brown chloroplasts are typical of heterokonts, having four membranes and containing pigments such as the carotenoid fucoxanthin. unique feature of diatom cells is that they are enclosed within a cell wall made of silica (hydrated silicon dioxide) called a frustule.

Introduction Morphology. Diatoms are algae with distinctive, transparent cell walls made of silicon dioxide hydrated with a small amount of water (Si02 + H20).Silica is the main component of glass and hydrated silica is very like the mineral opal, making these algae, often called algae in glass houses more like algae in opal houses.iatoms have been placed in the division Bacilliariophyta, which is distinguished by the presence of an inorganic cell wall composed of hydrated silica. There are an estimated 20,000 to 2 million species of diatom on Earth.

Diatoms Diatoms are microscopic, single-celled algae that have intricate glass-like outer cell walls partially composed of silicon. Different species of diatom can be identified based upon the structure of these walls. Many diatom species are planktonic, suspended in the water column moving at the mercy of water currents.

What are 4 uses of diatom cell walls? 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!

Diatom Diatoms are a major group of algae, and are among the most common types of phytoplankton. Diatoms are unicellular, although they can form colonies in the shape of filaments or ribbons (e.g. Fragilaria), fans (e.g. Meridion), zigzags (e.g. Tabellaria), or stars (e.g. Asterionella).iatoms are a widespread group and can be found in the oceans, in freshwater, in soils and on damp surfaces. Most live pelagically in open water, although some live as surface films at the water-sediment interface (benthic), or even under damp atmospheric conditions.

Diatoms are made of _____, which is used for industrial processes.? Best Answer: c)silica. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide) called a frustule. Silica, also known as silicon dioxide (the same as quartz or glass). It would be more correct to say that the skeletons of diatoms are made of silica.
