Protozoans: Characteristics and Classification

This video from Mumu Math and Science discusses protozoa, a type of animal-like protist. Protozoa are heterotrophs, meaning they cannot produce their own food, and are mostly unicellular, living in moist environments. The video explores three types of protozoans: ciliates, which move using tiny hairs called cilia; sarcodines, which move by oozing, with amoebas as a famous example; and flagellates, which use a whip-like structure called a flagellum for movement, with giardia as an example. The video concludes by summarizing the characteristics of protozoa and encouraging viewers to subscribe for more educational content.
