Verified step by step guidance

Begin by understanding the structure and function of cilia and flagella. Both are hair-like structures that protrude from the surface of certain cells and are involved in movement.

Recognize that the movement of cilia and flagella is powered by the cytoskeleton, which is a network of protein fibers within the cell that provides structural support and facilitates movement.

Identify the key components of the cytoskeleton involved in the movement of cilia and flagella. These structures primarily rely on microtubules, which are cylindrical tubes made of tubulin proteins.

Understand the role of dynein, a motor protein that interacts with microtubules. Dynein uses energy from ATP to change shape and move along the microtubules, causing the bending motion necessary for cilia and flagella movement.

Conclude that the interaction between microtubules and dynein is essential for the movement of cilia and flagella, as dynein's activity causes the microtubules to slide against each other, resulting in the bending and waving motion.
