They can also look very different and meld into any of the other competitors mentioned above. The larger one is contained within a groove called 'cingulum' (or girdle) which encircles the cell body and the smallest is perpendicular to the first one running from the center to posterior end of cell. Dinoflagellates are the most common cause of algal blooms in salt water. Dinoflagellates are unicellular and eukaryotic. Their Support is real people, and they are always friendly and supportive. Plankton The greatest concentrations of dinoflagellates in the phytoplankton (10 7 -10 8 /l) occur in temperate coastal waters subject to transient periods of vertical stability (Taylor et al. 3. Dinoflagellate eye-like ocelloids are built from pre-existing organelles of disparate origin, including a cornea-like layer made of mitochondria and a retinal body made of anastomosing plastids. Their cell walls are made of silica like plants.-C. They can produce harmful toxins.-D. Most dinoflagellates have a type of outer covering called amphiesma, which is made of multiple inner and outer membranes, and in between those membranes there are vesicles which can have thecal plates, which could be considered like a coat of armor. 2. Mobile dinoflagellates whirl through the water in search of energy, and often cluster in large amounts called blooms.
