Final answer:
Cilia and flagella are organelles of locomotion in eukaryotic cells. They contain microtubules and motor proteins that enable movement.
Step-by-step explanation:
Cilia and flagella are organelles of locomotion in eukaryotic cells. Both cilia and flagella contain microtubules and motor proteins that allow them to move. Flagella are long, hair-like structures that move an entire cell, while cilia are shorter and can either move entire cells or substances along the cell's surface.
