Ceratium hirundinella. Ceratium species are characterized by their horns and two flagella located in the transverse and longitudinal positions. Ceratium tripos is recognisable by its U-shaped horns. Ceratium species belong to the group of dinoflagellates known as Gonyaulacales, meaning they contain armored plates. [2]

Ceratium, genus of single-celled aquatic dinoflagellate algae (family Ceratiaceae) common in fresh water and salt water from the Arctic to the tropics. As dinoflagellates, the organisms have two unlike flagella and have both plant and animal characteristics; their taxonomic placement as algae is contentious.

2024年9月29日 · The genus Ceratium includes species of freshwater and marine dinoflagellates. Most species of Ceratium are unicellular organisms that are characterized by their armored plates, two flagella, and horns. Species of Ceratium are found worldwide and are of concern due to their blooms. Contents

Ceratium cells are photosynthetic but also contain vacuoles that suggest phagotrophy. Aplanospores (no flagella) are common, often after blooms. C. hirundinella has angular spores that are uninucleate, thick walled, and packed with glycogen as a storage reserve.

The largest dinoflagellate blooms in both lakes and the ocean are formed by species of the large, armored genus Ceratium during the autumn. For unknown reasons, grazing pressure on this genus is low, suggesting that survival rather than fast growth rates is the major reason for bloom build up over the late summer.

The genus Ceratium includes species of freshwater and marine dinoflagellates. Most species of Ceratium are unicellular organisms that are characterized by their armored plates, two flagella, and horns. Species of Ceratium are found worldwide and are of concern due to their blooms.

Ceratium is a unicellular organism and a member of the family Ceratiaceae, commonly known as dinoflagellates. Dinoflagellates are usually considered algae but mostly are marine planktons. Ceratium genus comprises a rather small number of about 7 freshwater dinoflagellate species.

Ceratium fusus is a solitary cell that contains numerous yellow-brown chloroplasts (EOL 2012). It has both sexual and asexual cycles of reproduction and is mixotrophic (Scott and Brandt 2011).

Description: Large, diverse genus. Armored, gonyaulacoid body, two to four hollow horns. Horns open or closed. Chloroplasts present. Distribution: Cosmopolitan, neritic, cold and warm waters. C. furca is very common in Monterey Bay and often forms dense blooms.

In this article we will discuss about the structure of ceratium. This will also help you to draw the structure and diagram of ceratium. (1) It is a fresh water as well as a marine form and is free living. (2) Body some what flattened and triradiate and is enclosed inside a shellot cellulose. The flagelia are two.
