Some protists live in the bodies of animals as parasites. Structure of Protists: Protists are [...]
The following points highlight the seven modes of nutrition in protists. The modes are: 1. Photosynthetic 2. Holozoic or Zoo-Trophic 3. Saprobic or Saprotrophic 4. Parasitic 5. Mixotrophic 6. Symbiotic 7. Pinocytosis. Modes of Nutrition # 1. Photosynthetic (Holophytic): In this mode, the organisms prepare their food from CO2 and water by utilizing sunlight with the help of photosynthetic pigments [...]
In this article we will discuss about:- 1. Habitat and Habits of Dinoflagellates 2. Structure of Dinoflagellates 3. Reproduction 4. Economic Importance. Habitat and Habits of Dinoflagellates: (i) The din-flagellates are important component of phytoplankton. Most of them are marine but some occur in fresh water. Some din flagellates such as Gymnodinium and Gonyaulax grow in large number in the [...]
