Light manipulation in a marine diatom SpringerLink
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. This material is then extruded to the cell exterior … See more A diatom (Neo-Latin diatoma) is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a … See more Diatoms are generally 2 to 200 micrometers in size, with a few larger species. Their yellowish-brown chloroplasts, the site of photosynthesis, are typical of heterokonts, … See more Reproduction and cell size Reproduction among these organisms is asexual by binary fission, during which the diatom divides into two parts, producing two "new" diatoms … See more • The modern oceanic silicon cycle Fluxes are in T mol Si y (28 million metric tons of silicon per year) Silica cycle See more Diatoms are protists that form massive annual spring and fall blooms in aquatic environments and are estimated to be responsible for about half of photosynthesis in … See more Most centric and araphid pennate diatoms are nonmotile, and their relatively dense cell walls cause them to readily sink. Planktonic forms in open water usually rely on turbulent mixing of the upper layers of the oceanic waters by the wind to keep them suspended in … See more Distribution Diatoms are a widespread group and can be found in the oceans, in fresh water, in soils, … See more WebDiatoms are single-celled algae. Diatoms are algae that live in houses made of glass. They are the only organism on the planet with cell walls composed of transparent, opaline silica.
