Dinoflagellates Classification

Dinoflagellates

Dino is a Greek word for ‘whirling ‘ and flagellate is a Latin word for ‘whip’ For example, to save the tiger, we save the whole forest. it has a tail-like structure and the motion it produces when it swims. Dinoflagellates have two whip-like tails called flagella used for movement. One flagellum lies longitudinally, and the other transversely in a furrow between the wall plates. The cell wall consists of stiff cellulose on the outer surface. They are mostly marine but can also be found in freshwater all around the world. Their population varies with latitude, temperature, salinity, and depth. Depending on the main pigment present in the cell, they appear red, yellow, green, blue, and brown. Most species of dinoflagellates are phototrophic, and the other few are mixotrophic (combining photosynthesis and phagocytosis)....

Dinoflagellates Classification

Dinoflagellates belong to the domain Eukaryota, classified under Kingdom Protista and phylum Dinoflagellata. Dinoflagellates are kept in the supergroup Chromalveolata and group Alveolata. They are characterized by ribosomal DNA sequences and flattened vesicles inside plasma membranes called alveoli....

Characteristics of Dinoflagellates

Dinoflagellates are unicellular, eukaryotic organisms. Most dinoflagellates are marine, but they are also found in freshwater. Their distribution depends on the pH level, temperature, salinity, and depth of the aquatic ecosystem. They show three modes of nutrition – phototrophic, heterotrophic, and mixotrophic. The flagella are responsible for locomotion and facilitate a spinning top-like motion. They possess an organelle called an eyespot that is light-sensitive. It provides them with a sense of direction. Dinoflagellates store food in the form of starch....
