Protozoan motility structures includeGroup of answer choicescilia and pseudopods only.cilia.flagella.cilia, flagella, and pseudopods.pseudopods.

Analyzing the Choices

1. Cilia: These are short, hair-like structures that help in movement and feeding. They can be found in many protozoans, like Paramecium.

2. Flagella: These are longer and whip-like structures that propel protozoans, such as Euglena or Trypanosoma.

3. Pseudopods: These are temporary projections of eukaryotic cells, commonly seen in amoebas, which extend and retract to allow movement and feeding.

Relevant Concepts

Protozoans are single-celled organisms that exhibit different forms of motility. The three types of structures that facilitate their movement are cilia, flagella, and pseudopods.

Determining the Correct Answer

Since protozoans can utilize all three types of motility structures—cilia, flagella, and pseudopods—the correct choice encompasses all forms of motility present in various protozoan species.

Final Answer

The correct option is: cilia, flagella, and pseudopods.
