Detailed explanation-1: -Animal-like protists are also known as Protozoa. Some are also parasites. The Protozoa is often divided into 4 phyla : Amoebalike protists, flagellates, ciliates, and spore-forming protists.

Detailed explanation-2: -Protozoa can be divided into four phyla based on their locomotion: Mastigophora, Sarcodina, Ciliophora, and Sporozoa.

Detailed explanation-3: -(c) Euglena uses a whip-like tail called a flagellum to propel itself. Some protists can move toward or away from a stimulus, a movement referred to as taxis. Movement toward light, termed phototaxis, is accomplished by coupling their locomotion strategy with a light-sensing organ.

Detailed explanation-4: -Zooflagellates are a third type of protists. They are animal-like and move by using flagella. Flagella are whip-like structures that spin quickly, working like a boat’s propeller to move the organism through water. Most zooflagellates have from one to eight flagella that help them move.
