Here's a breakdown:
* Cilia: These are short, hair-like projections that extend from the cell surface. They move in a coordinated, wave-like fashion, propelling fluids or particles along the cell surface.
* Flagella: These are longer, whip-like projections that are typically found in single numbers. They are responsible for locomotion (movement) of the cell itself.
While both cilia and flagella are involved in movement, their roles and structures differ. Cilia are primarily for moving substances along the cell surface, while flagella are for cell movement.
