Protozoa Classification and Characteristics

The video introduces protozoa, explaining their classification within the Protista kingdom. Protozoa are unicellular, eukaryotic organisms, often heterotrophic, and found in aquatic environments. They can be free-living or parasitic. The video discusses their classification based on locomotion, including flagellates, amoebas, and sporozoans, and highlights diseases caused by parasitic protozoa, such as malaria and Chagas disease. Preventive measures against protozoan diseases are also covered.
