Verified step by step guidance

Understand the structure of cilia and flagella: Both cilia and flagella are hair-like structures that extend from the surface of many eukaryotic cells. They are primarily composed of microtubules arranged in a '9+2' pattern, which is crucial for their movement.

Identify the role of microtubules: Microtubules are part of the cytoskeleton and are made up of tubulin proteins. They provide structural support and are essential for the movement of cilia and flagella.

Recognize the function of motor proteins: Motor proteins, such as dynein, interact with the microtubules in cilia and flagella. These proteins convert chemical energy from ATP into mechanical work, enabling the bending and movement of these structures.

Differentiate between the options: Actin is another cytoskeletal element involved in muscle contraction and cell movement, but not directly in the movement of cilia and flagella. Pseudopodia are temporary projections of eukaryotic cell membranes, and mitochondria are organelles responsible for energy production, neither of which are directly involved in cilia and flagella movement.

Conclude the interaction: The movement of cilia and flagella is due to the interaction between microtubules and motor proteins, specifically dynein, which causes the sliding of microtubules against each other, resulting in movement.
