Question

4 protists may move by check all that apply cilia. flagella. pill pseudopods jointed appendages

Explanation:

• Cilia: Some protists (e.g., paramecium) have cilia - short, hair - like structures that beat in coordinated waves to move the organism.
• Flagella: Flagellated protists (e.g., euglena) use long, whip - like flagella for locomotion.
• Pseudopods: Amoeboid protists (e.g., amoeba) extend pseudopods (false feet) which help in movement by cytoplasmic streaming into these extensions.
• Pili: These are structures mainly found in bacteria (not protists) and are involved in functions like attachment (fimbriae - a type of pili) or conjugation (sex pili).
• Jointed appendages: These are characteristic of arthropods (a group in the animal kingdom), not protists.

Answer:

cilia, flagella, pseudopods
