FACTS ABOUT DINOFLAGELLATES Dinoflagellates are unicellular plankton. They belong to the phylum dinoflagellata (dinophyta). They have a dinokaryotic nucleus. Contrary to prokaryotic or eukaryotic, their chromosomes are permanently condensed. The largest dinoflagellates are the Noctiluca. It is 2mm in size. There are over 20,000 species of dinoflagellates The Zooxanthellaae gives coral its color. Dinoflagellates belong to the kingdom Protista. Protists are organisms that are similar to organisms in Animal, Plants, and fungus kingdoms, but they are different. For example, a Protist may have chlorophyll but move on its own, or it may move on its own, but is unicellular.
CONTINUED FACTS ABOUTDINOFLAGELLATES 90% of dinoflagellates live in the ocean. All dinoflagellates are autotrophs, which means they use photosynthesis. Some even live in snow. Dinoflagellate means whirling flagella.
CHARACTERISTICS OFDINOFLAGELLATES Dinoflagellates have two flagella. They spin in a top like motion. When disturbed, they glow causing the ocean to light up. However, not all dinoflagellates are harmless. Some such as Gonyaalax, Gymnodinium, Alexandrium, and many more have a harmful algal blooms which causes red tides. The chemical reaction that causes their glow is called Bioluminescene. These algal blooms release toxins that are harmful to sea creatures and humans if they eat seafood that have the toxin. Dinoflagellates are golden brown or summer green.
The anatomy(parts)of dinoflagellatesFlagellum- a long “tail” used formovement.Golgi Body- Used for “shipping”particles around the cell.Mitochondria- Used to breakdown particles And release energy.Ribosomes- makes proteinsChloroplasts- Used to make foodby taking oxygen and carbon andturning it into glucose.Sulcum- A belt-like part thatconnects the connects the upperplate and the lower plate.
REPRODUCTIONDinoflagellates reproduce asexually or by binary fission.First, the parent cell expands. Next, the DNA is replicated (copied).Then, the two DNA strands attach tothe cell membrane. After, the parent cellExpands even more. Finally, theCell membrane meets at the center andSplits into two new identical cells.
