PROTOZOANS
An amoeba and a Volvox are two examples of protists. The amoeba is heterotrophic (does not make its own food), and the Volvox is autotrophic (makes its own food through photosynthesis).
The two major groups of protists are protozoa (animal-like protists) and algae (plant-like protists). Protozoa are unicellular organisms that can be parasitic or free-living, while algae are photosynthetic protists that can be unicellular or multicellular.
Two organisms classified as protists are amoebas and paramecia. Amoebas are unicellular organisms that move and feed using pseudopodia, while paramecia are also unicellular but have a characteristic slipper shape and are covered with cilia that aid in movement and feeding. Both belong to the kingdom Protista, which includes a diverse range of eukaryotic microorganisms.
Dinoflagellates and euglenoids differ from other plantlike protists primarily in their structure and motility. Dinoflagellates typically have two flagella for movement and possess unique cell walls made of cellulose plates, contributing to their distinctive appearance. Euglenoids, on the other hand, have a flexible pellicle instead of a rigid cell wall, allowing for greater shape variability. Additionally, many euglenoids can photosynthesize using chloroplasts, but they can also switch to heterotrophic feeding in the absence of light, showcasing their adaptability compared to other plantlike protists.
All protists havee nuclei and are unicellular.
Freshwater protists with two flagella that can be photosynthetic or heterotrophic are called euglenoids. They are single-celled organisms that can switch between autotrophic and heterotrophic modes of nutrition depending on environmental conditions.
Two major types of nutrition in protists are autotrophic and heterotrophic. Autotrophic protists can produce their own food through photosynthesis or chemosynthesis, while heterotrophic protists obtain their nutrition by consuming organic matter or other organisms.
Fungi has cell walls that are composed of chitin. Protists lack cell walls entirely.Fungi are sessile. Protists can be sessile or mobile.Fungi are heterotrophic. Protists are heterotrophic, although some are autotrophic (which may suggest that the first plants derived from protists).
