Question

____________________ are protozoa that use cilia to move.

○ zooflagellates

○ sarcodina

○ pseudopods

○ ciliates

Explanation:

To solve this, we analyze each option:

• Zooflagellates use flagella for movement, not cilia.
• Sarcodina (amoebas) use pseudopods for movement.
• Pseudopods are structures (not a group of protozoa) used by some protozoa for movement.
• Ciliates are a group of protozoa that use cilia for locomotion.

D. ciliates
