The DNA does have repeated sequences like other eukaryotes, but does not seem to have histones (basic proteins which the DNA coils around) -- though reports vary as to whether or not basic proteins exist in the group. Introduction to the Dinoflagellata. Dinoflagellates are unicellular protists which exhibit a great diversity of form. The largest, Noctiluca, may be as large as 2 mm in diameter!

Ceratium-soorten hebben geelbruine chloroplasten. Bij mariene soorten is er anisogamie met een zygotische nucleaire faseverandering. Vegetatief vermenigvuldigen ze zich door een schuine lengtedeling, waarbij de bepantsering schuin op de sulcus wordt opgesplitst en vervolgens wordt aangevuld met de cellen.

Pycnocline (pycno- dense; -cline gradient) The depth in the water column at which the density changes rapidly.This density gradient can be caused by temperature (thermocline), salinity (halocline) or both. Because of the difference in density, bodies of water will often stay as distinct layers and not mix. ABSTRACT. Ceratium furca is a primarily photosynthetic dinoflagellate also capable of ingesting other protists.

Microspheres added to natural plankton assemblages at a concentration of 5 x 10 6 to 10 7 ml-1 were rapidly ingested by a variety of planktonic organisms including small flagellates, ciliates, dinoflagellates, ebriids and amoebae.

Previously the genus contained also a large number of marine dinoflagellate species. However, these marine species have now been assigned to a new genus called Tripos. Ceratium dinoflagellates are characterized by their armored plates, two flagella, and horns. They are found worldwide and are of concern due to their blooms. Ceratium Schrank (Figs.
