What are benthic diatoms?
Benthic diatoms are microalgae used worldwide for water quality assessment. They are of particular interest in the context of bioassessment because of their taxonomic diversity and different species sensitivity and resistance to pollution.
Are dinoflagellates benthic or planktonic?
planktonic
Neither plant nor animal, dinoflagellates are unicellular protists; most exhibit the following characteristics: They are planktonic. Ninety percent of all dinoflagellates are marine plankton. Others are benthic, symbiotic, or parasitic.
Where are diatoms and dinoflagellates found?
Diatoms can generally grow throughout the Baltic Sea, but dinoflagellates are restricted to marine and brackish waters.
Where are benthic diatoms found?
Diatoms are found in almost all aquatic environments as long as light is available for their photosynthesis.
Is Coral a benthic?
3.1 Coral Reef Ecosystem. Coral reefs are archetypical benthic ecosystem found in warm, oligotrophic, shallow depth in tropical waters.
What does benthic refer to?
The term benthic refers to anything associated with or occurring on the bottom of a body of water. The animals and plants that live on or in the bottom are known as the benthos.
What are the types of dinoflagellates?
Dinophyceae
Syndiniales
Dinoflagellates/Lower classifications
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 diatoms a type of dinoflagellates?
Summary – Diatoms vs Dinoflagellates Diatoms and dinoflagellates are types of phytoplankton. They are single-celled algae. Diatoms have a theca covering the cell, which acts as an external cell wall. Dinoflagellates have special features such as the ability to produce neurotoxins and ability for bioluminescence.
What is the common between diatoms and dinoflagellates?
A similarity between diatoms and dinoflagellates is that they are both types of phytoplankton that can be found in seawater. Both dinoflagellates and diatoms reproduce using photosynthesis and they both also produce significant amounts of new organisms every year. A difference between them is their physical appearance.
Are dinoflagellates heterotrophic or autotrophic?
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 …
Who discovered diatoms?
Notable amongst these are the works of Cleve, Ehrenberg, Grunow, Schmidt and Van Heurck. In the early twentieth century fossil diatoms were first studied and, most famously, Hustedt (1927-66) produced a taxonomic and ecological study of diatoms which remains a key reference today.
