Dinoflagellates are protists which have been classified using both the International Code of Botanical Nomenclature (ICBN) and the International Code of Zoological Nomenclature (ICZN), approximately half living dinoflagellate species are autotrophs possessing chloroplasts and half are non-photosynthesising heterotrophs ...

What group is dinoflagellates in?
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.
How do dinoflagellates feed?
Many dinoflagellates are photosynthetic, manufacturing their own food using the energy from sunlight, and providing a food source for other organisms. ... Some species are parasites on algae, zooplankton, fish or other organisms.
What type of protist is dinoflagellates?
Dinoflagellate is any diverse flagellate protists comprising the taxon Dinoflagellata, or Pyrrophycophyta, typically characterized by being single-celled and with two dissimilar flagella during at least part of their life cycle.
What type of nutrition is shown by dinoflagellates?
Nutrition among dinoflagellates is autotrophic, heterotrophic, or mixed; some species are parasitic or commensal. About one-half of the species are photosynthetic; even among those, however, many are also predatory.
Why are dinoflagellates classified as autotrophs and Heterotrophs?
Why are dinoflagellates classified as autotrophs and heterotrophs? Since dinoflagellates both make and ingest food, they are considered to be autotrophs as well as heterotrophs. Diatoms, however, are strictly autotrophs.
Are dinoflagellates autotrophic or heterotrophic quizlet?
What are dinoflagellates? ✔ Dinoflagellates are a group of mostly marine singlecelled alveolate protists. Some are heterotrophs. Others are photosynthetic members of plankton or symbionts in reef-building corals.
Is Ceratium autotrophic or heterotrophic?
Growth. Species of Ceratium are mixotrophic, meaning they are both photosynthetic and heterotrophic, consuming other plankton.
Are dinoflagellates eukaryotic or prokaryotic?
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.
What copepods eat dinoflagellates?
Copepodes such as Acartia tonsa, eat diatoms and dinoflagellates predominately. Dinoflagellate often forms blooms when conditions are good (light plus ?) for their growth and some species release toxins into the water which paralyze or kill animals, including copepods.
Are dinoflagellates phytoplankton or zooplankton?
The most common phytoplankton are diatoms, photosynthesizing dinoflagellates, and blue-green algae. Zooplankton include protozoans such as foraminiferans, radiolarians, and non-photosynthesizing dinoflagellates as well as animals like tiny fish and crustaceans such as krill.
Is dinoflagellates unicellular or multicellular?
Dinoflagellates are unicellular and possess two dissimilar flagella arising from the ventral cell side (dinokont flagellation).
Why are dinoflagellates classified as protists?
Why are dinoflagellates classified as protists? They are single-celled organisms with two flagella; their structure (they have cell walls) and their life processes contribute to their classification as protists. They can both eat and create their own food.
Do dinoflagellates have chlorophyll?
Dinoflagellates are unicellular flagellated algae belonging to the phylum Pyrrophyta. Their cells contain chlorophylls a and c. They occur in both freshwater and marine habitats. ... Dinoflagellates produce two types of toxins.
Are dinoflagellates algae or protozoa?
Dinoflagellates are microorganisms that are regarded as algae. Their wide array of exotic shapes and, sometimes, armored appearance is distinct from other algae. The closest microorganism in appearance are the diatoms . Dinoflagellates are single-celled organisms.
