Detailed explanation-1: -Protist cells can be distinguished from plant, animal and fungal cells by their ability to move on their own. They may move using one or more tails (flagella), tiny hairs on the cell membrane (cilia) or long, arm-like extensions of the cell membrane (pseudopodia).

Detailed explanation-2: -Animal-like protists are commonly called protozoa (singular, protozoan). Most protozoa consist of a single cell. They are animal-like because they are heterotrophs, and are capable of moving.

Detailed explanation-3: -Protists, like fungi, can be unicellular or multicellular. Examples of unicellular protists include amoebas and euglenas. Examples of multicellular protists include many types of algae, including giant kelp.

Detailed explanation-4: -Protists are unicellular organisms, whereas animals are multicellular organisms. Protists are microscopic, whereas animals are visible with naked eyes and found in various sizes and shapes.
