A student is revising Animal Diversity-I: a lab manual lists Euglena, Amoeba, Entamoeba, Plasmodium, Trypanosoma, and Paramecium for slide study. What should the student write in the answer sheet?

Prepared slides are useful for microscopic protists because they allow students to observe body shape, locomotory structures, nuclei, and parasitic stages that are difficult to see with the naked eye. This MCQ belongs to the Practical zoology topic in Animal Diversity-I and is written to test concept understanding rather than memorized wording.
