What type of plankton is Ceratium?
What type of plankton is Ceratium?
Ceratium, genus of single-celled aquatic dinoflagellate algae (family Ceratiaceae) common in fresh water and salt water from the Arctic to the tropics. Members of the genus form an important part of the plankton found in temperate-zone seas, and several are known to cause red tides and water blooms.
Where are Ceratium found?
Ceratium are aquatic organisms, living in both marine and freshwater environments. They are most common in temperate areas, but can be found all over the world. Ceratium are found in the upper regions of the water, where there is enough light for photosynthesis.
Does Triceratium cause red tide?
Option-C-Triceratium: Triceratium too is not responsible for causing red tides.
What causes red tide * 1 point Ceratium Triceratium Gonyaulax all of these?
Hint: The red tides caused by the dinoflagellates. These are serious because this organism produces saxitoxin which accumulates in shellfish and if ingested may lead to paralytic shellfish poisoning (PSP) and can lead to death.
Is Gonyaulax photosynthetic?
Gonyaulax catenella happens to be photoautotrophic, meaning this organism converts light into food energy through photosynthesis. Unlike other dinoflagellates, Gonyaulax catenella does not possess an eyespot. Instead, photosynthetic regions are located near the base of its flagella.
Are there dinoflagellates that are toxic to humans?
This phenomenon is called a red tide, from the color the bloom imparts to the water. Some colorless dinoflagellates may also form toxic blooms, such as Pfiesteria. Some dinoflagellate blooms are not dangerous. Bluish flickers visible in ocean water at night often come from blooms of bioluminescent dinoflagellates,…
How are dinoflagellates with and without a dinokaryon classified?
Dinoflagellates with a dinokaryon are classified under Dinokaryota, while dinoflagellates without a dinokaryon are classified under Syndiniales.
What kind of habitat does a dinoflagellate live in?
Usually considered algae, dinoflagellates are mostly marine plankton, but they also are common in freshwater habitats. Their populations are distributed depending on sea surface temperature, salinity, or depth.
Are there grooves in the dinoflagellate desmokont flagella?
In dinoflagellate species with desmokont flagellation (e.g., Prorocentrum ), the two flagella are differentiated as in dinokonts, but they are not associated with grooves.
