Dinoflagellates are unicellular eukaryotes. They come under the kingdom Protista. They are known for bioluminescence and creating red tide in the ocean.

In laboratories sexual reproduction may be induced by nutrient, temperature or light reduction. In nature sexual reproduction is known to occur in late summer and autumn and in the late stages of blooms. Preparation Techniques

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. Although sexual processes have been demonstrated in a few genera, reproduction is largely by binary or multiple fission. Dinoflagellates have a nuclear variant called a dinokaryon. The chromosomes in the dinokaryon are highly condensed throughout the cell cycle and do not have typical histones.

Dinoflagellates reproduction

During normal conditions, they reproduce just like any cell, by asexual division. This means that new dinoflagellates break off from old Reproduction Dinoflagellates reproduce primarily by a process called fission, though some sexual and asexual reproduction may also take place at this time. Any type of these reproduction processes happen mainly in the warmest parts of summer months. Millions of cells may be produced at a single time. Dinoflagellates are haploid during the majority of their life cycle. This means cells contain a single set of chromosomes.

Dinoflagellates essentially have two means of reproduction.

In laboratories sexual reproduction may be induced by nutrient, temperature or light reduction. In nature sexual reproduction is known to occur in late summer and autumn and in the late stages of blooms. Preparation Techniques

A classification scheme based on nameless ranked systematics for dinoflagellate levels above genus was proposed. Higher ranks were It is common during asexual reproduction for the parent cell to shed part or all of its cell wall.

Poor water quality can attribute to their rapid reproduction.

In haplontic dinoflagellates, the asexual reproduction may be by desmoschisis or by As the dinoflagellates reproduce, the bioluminescent glow will intensify. A healthy dinoflagellate culture should be divided every 3 to 4 weeks. To divide a culture Gambierdiscus toxicus is an armoured, marine, benthic dinoflagellate species.

There are many forms, but the kind that gives reef keepers fits is a snot-like algae substance that attaches to rocks, sand, power Autrefois hors de portée de la science, les connaissances sur la Reproduction des Dinosaures se dévoilent en étudiant leurs plus proches parents vivants.

However, sexual reproduction is common in some genera, which are mostly anisogamous or isogamous. Notably, dinoflagellates that reproduce sexually may go through a resting phase and turn into a hypnozygote.
