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.

Plankton Phytoplankton. Diatoms are the most common type of phytoplankton. They 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.hey are single-celled yellow algae whose cell walls contain a lot of silica, glass-like substance.

- All diatom skeletons are made of silica and consist of two parts or frustules that fit inside each other like a petri dish: the epitheca and the hypotheca (Alexopoulos, 1967). The hypotheca is smaller and fits inside the larger epitheca.

- The plant-like protists are commonly referred to as algae and can be either single-or multi-celled. Algae contain chlorophyll and carry out the process of photosynthesis. Diatoms are single-celled algae that excrete a cell wall made of silica.he fungus-like protists are the slime molds and water molds. They are mostly single-celled organisms that live in the moist soil of forest floors and compost piles. These heterotrophs absorb nutrients from decaying organic matter and move in the same fashion as amoebas by extending and pulling with pseudopodia.

- Similar to many other algae, they can live as unicellular organisms, colonial, or filamentous. Unlike most algae, though, they have a solid shells made of silica. Because of such shells, diatoms have major economic importance in industry while also having a major role in biological and chemical processes. Almost all of the extant and extinct species of Bacillariophyta are aquatic.

Difference Between Kelp and Seaweed Though kelp is a kind of seaweed, it is different from seaweed in many aspects. Kelp is also referred to as large seaweed, which belongs to the brown algae. Classified in the Laminaria order, about 300 genera of Kelp are known. Some of the kelp species are very long, and can even form kelp forests. Though kelp appears like a plant, they are not classified under terrestrial plants, but as Protista.

What are Diatoms? Diatoms are unicellular algae which form distinct and beautiful cell walls from silica. They are widely distributed throughout the upper layers of the oceans of the world, and can also be found in fresh water or moist environments, such as the undersides of plants.

Diatoms Diatoms are a major group of eukaryotic algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons (e.g. Fragillaria), fans (Meridion), zigzags (Tabellaria), or stellate colonies (Asterionella). Diatoms are producers.

Diatom Bloom Diatoms are sometimes referred to as microalgae, brown algae, or golden algae and can be very unsightly to look at in a reef tank.We are currently experiencing a “bloom” of diatoms and researching the possible causes and solutions. From my reading, these are the possible causes of a diatom bloom:Having a tank with silica present can cause diatom problems that remain present until all of the silica is used up.iatoms are sometimes referred to as microalgae, brown algae, or golden algae and can be very unsightly to look at in a reef tank.

- An example of a freshwater environment is a lake, pond, a river or a stream. Microalgae grow in both saltwater and freshwater. Diatoms grow in freshwater environments especially lakes or ponds. Dinoflagellates can be found growing in saltwater environments in the sea.Red, green and brown macroalgae are found growing in saltwater.The “ecosystem” can be desribed as a community made up of living (algae, plants, animals, insects) and non-living organisms (rocks, tides, weather, nutrients, light).n example of a freshwater environment is a lake, pond, a river or a stream.

The Difference Between Seaweed And Kelp Seaweed is broken down into three different types—red, green, and brown; their different colors reflect the different type of light they will readily absorb for photosynthesis, which in turns dictates how deep or how close to the surface they generally grow.

What is a difference between desmids and diatoms? Diatomic molecule is a molecule that is made up of only 2 atoms. Triatomic molecule is a molecule that is made up of only 3 atoms. Thus, the difference is that a diatomic molecule is made up of only 2 atoms while a triatomic molecule is made up of only 3 atoms.

- Marine Algae Seaweed is a term applied to multicellular, marine algae which are large enough to be seen by the eye unaided. Some can grow to up to 60 metres in length. Seaweeds include members of the red, brown and green algae. They are members of the kingdom Protista meaning they are not Plants. They do not have the vascular system (internal transport system) of plants and do not have roots, stems, leaves and flowers or cones.

- Remarkable features of dinoflagellates seem to be the rule rather than the exception. Dinoflagellates may possess ejectile organelles similar to the cnidarian nematocysts. Many have numerous structures near the periphery of their cell interior called trichocysts, features similar to those found in ciliates. red tide, more properly termed a harmful algal bloom, is somewhat of a misnomer since the water rarely turns red but more usually a tint of orange, resulting from the rapid bloom and dense populations (up to 100 million cells/l) of one or more of several species of dinoflagellates (or diatoms).

Introduction 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.early all diatoms are microscopic-cells range in size from about 2 microns to about 500 microns (0.5 mm), or about the width of a human hair (note that one micron is equal to 10 -6 meter).

Bacillariophyta Diatoms are set up with a cell wall made up of silica and the diatom itself is a single-celled photosynthetic protist. Very little is known about how the cell wall is made, but scientists are researching it to hopefully find a way to reproduce the thin glass-like wall for nanotechnology.heir cell wall is not soluble in water so most of them end up on the bottom of lakes and ponds. This sediment will build up and become fossilized rock. This rock is used commercially for everything from abrasives to paper to fertilizer. There are about 10,000 different species of diatoms.
