What is a diatom and what does it do?
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.
What is diatoms in biology?
A diatom is a unicellular eukaryotic alga characterized by the siliceous covering and symmetry. Diatoms are mostly aquatic, being found in fresh, brackish, and saltwater. They comprise the taxonomic class Bacillariophyceae. They may be solitary or in colonies.
Where do diatoms come from?
Diatoms are a widespread group and can be found in the oceans, in fresh water, in soils, and on damp surfaces. They are one of the dominant components of phytoplankton in nutrient-rich coastal waters and during oceanic spring blooms, since they can divide more rapidly than other groups of phytoplankton.
Where is diatom found?
Diatoms are photosynthesising algae, they have a siliceous skeleton (frustule) and are found in almost every aquatic environment including fresh and marine waters, soils, in fact almost anywhere moist.
How do diatoms help humans?
Diatoms are also useful in forensic studies. If a person has drowned then diatoms are able to enter the human body. ... The similarity of the diatoms present in the water that the body is found in and the diatoms present in the body can help to discover whether the body was moved.
How do diatoms breathe?
Through carbon fixation, diatoms remove carbon dioxide (CO2) from the atmosphere. The CO2 is converted to organic carbon in the form of sugar, and oxygen (O2) is released. We breathe the oxygen that diatoms release.
What are diatoms for kids?
Diatoms (Greek: dia = through + temnein = to cut: "cut through") are a big group of eukaryotic algae. They are one of the most common types of phytoplankton. Most diatoms are unicellular, although some form chains or simple colonies. Diatom cells are encased within a unique cell wall made of silica (SiO2).
Are there diatoms in drinking water?
Many species float among plankton in the ocean, some live in freshwater, and a few are found in moist soils. In Montana, diatoms are abundant in our lakes, rivers and streams. Diatom communities are influenced by environmental change, which makes them good indicators of water quality.
Are diatoms algae or protozoa?
Diatoms are considered algae and can be colonial or live as a single cell. They are characterized by their beautiful intricate shells, which are made of silica and can persist when the organism dies.
Are diatoms plants or animals?
Diatoms are an enigma. Neither plant nor animal, they share biochemical features of both. Though simple single-celled algae, they are covered with elegant casings sculpted from silica.
What are two special things about diatoms?
Diatoms are also impressive shell builders. They transform dissolved silicon into a silica almost identical to the gemstone opal. Diatoms contribute enormous amounts of oxygen to our atmosphere and even offer various functions when dead, as diatomaceous earth.
Can humans eat diatoms?
Food-grade diatomaceous earth is safe to consume. It passes through your digestive system unchanged and does not enter the bloodstream. However, you need to be very careful not to inhale diatomaceous earth.
How do diatoms digest?
Unlike many other types of phytoplankton and marine organisms, diatoms don't have body parts that allow them to swim . They obtain food by absorbing nutrients from ocean water, which is a very competitive process.
Are diatoms harmful to humans?
Diatoms that can form harmful algal blooms are a concern. When humans ingest or absorb the toxins produced, it can become harmful. For instance, diatoms in the genus Pseudo-nitzschia secretes a neurotoxin called domoic acid, which can cause amnesic shellfish poisoning.
