dinoflagellates, Noctiluca, Oxyrrhis, and Dinophysis, contain cryp-tic plastidial metabolisms and lack alternative cytosolic pathways, suggesting that all free-living dinoflagellates are metabolically de-pendent on plastids. This finding led us to propose general mech-anisms of dependency onplastid organelles in eukaryotes that have

Dinoflagellates: A Brief Overview. Though most dinoflagellates are marine planktons, some of them are also found in freshwater ecosystems. They are known to possess the characteristics of both flora and fauna and serve as a crucial link in the food chain.

Dinoflagellates are single-celled organisms that have two distinctive flagella during at least part of their life cycle and/or a special type of nucleus called a dinokaryon (Fensome et al., 1993b). They are probably best known as a principal cause of "red tides" and paralytic shellfish poisoning. Most dinoflagellates have a complex life cycle involving several stages, asexual and sexual, motile and non-motile (see Figure D41).During the course of sexual reproduction, some species form a diploid cell (i.e., with 2n chromosomes following the fusion of the gametes) that is protected within a cyst, permitting survival of the organism during a dormancy period of variable length (Fensome et Hitta perfekta Ceratium Dinoflagellates bilder och redaktionellt nyhetsbildmaterial hos Getty Images.

Dinoflagellates are a group of unicellular protists that can be identified using the light microscope, and are (usually) recognized by their golden-brown plastids, assimilative cell with indented waist, distinctive swimming pattern, and relatively large nucleus that contains visible chromosomes. Dinoflagellates are unicellular eukaryotes with a fossil record tracing back to the early Cambrian.

The dinoflagellates are a large group of flagellate protists.About half are photosynthetic, the rest are mostly heterotroph predators of other protists. The ones which are photosynthetic are sometimes loosely called 'algae'; the one which are predators are sometimes loosely called 'protozoa'. They have been classified as an order, a class and a phylum by different authors.

It is known to cause bioluminescence in the ocean. Dinoflagellates are found in fresh and saltwater and, in large numbers, can produce dangerous levels of neurotoxic chemicals.

Nowadays around 2000 species live mainly in the sea but freshwater dinoflagellates exist too. Most dinoflagellates have complex life cycles with several steps, 

Most are marine, though some live in freshwater habitats. Dinoflagellates are unicellular eukaryotes with a fossil record tracing back to the early Cambrian. They are widespread in marine and freshwaters, where they present a great diversity including autotrophic, heterotrophic, mixotrophic, parasitic, and symbiotic species. 2021-02-24 · Dinoflagellates are food chain producers and, as a component of plankton, provide an important source of nutrition for aquatic primary consumers. Dinoflagellate Anatomy. Dinoflagellate anatomy is complex, even though these are unicellular eukaryotes. As part of the earliest forms of life, they straddle the border between plant and animal.
