The plankton can either be collected from a body of water or cultured, though the former method is seldom used. Phytoplankton is used as a foodstock for the production of rotifers, [55] which are in turn used to feed other organisms. Phytoplankton is also used to feed many varieties of aquacultured molluscs, including pearl oysters and giant clams.
Dinoflagellate. The dinoflagellates (from Ancient Greek δῖνος (dînos) 'whirling' and Latin flagellum 'whip, scourge') are a monophyletic group of single-celled eukaryotes constituting the phylum Dinoflagellata[5] and are usually considered protists. Dinoflagellates are mostly marine plankton, but they are also common in freshwater habitats.
Plankton are the building blocks of life in the sea. Everything depends on them. Phytoplankton are microscopic plants that can be as small as one cell. They contain chlorophyll, which allows them ...
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. [40] 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 and added to ...
Plankton. Zooplankton are the heterotrophic component of the planktonic community (the "zoo-" prefix comes from Ancient Greek: ζῷον, romanized: zôion, lit. 'animal'), having to consume other organisms to thrive. Plankton are aquatic organisms that are unable to swim effectively against currents.
The organisms responsible for primary production are called primary producers or autotrophs. Most marine primary production is generated by a diverse collection of marine microorganisms called algae and cyanobacteria. Together these form the principal primary producers at the base of the ocean food chain and produce half of the world's oxygen.
Plankton. The Radiolaria, also called Radiozoa, are protozoa of diameter 0.1–0.2 mm that produce intricate mineral skeletons, typically with a central capsule dividing the cell into the inner and outer portions of endoplasm and ectoplasm. The elaborate mineral skeleton is usually made of silica. [1]
