Verified step by step guidance

Understand the structure and function of cilia and flagella: Both cilia and flagella are hair-like structures that extend from the surface of many eukaryotic cells. They are involved in movement and are essential for various cellular processes.

Identify the cytoskeletal components: The cytoskeleton is composed of three main types of filaments: actin filaments (microfilaments), intermediate filaments, and microtubules.

Focus on microtubules: Microtubules are cylindrical structures made of tubulin proteins. They are the largest of the cytoskeletal components and play a crucial role in maintaining cell shape, enabling intracellular transport, and facilitating cell division.

Relate microtubules to cilia and flagella: Both cilia and flagella have a core structure known as the axoneme, which is primarily composed of microtubules arranged in a '9+2' pattern. This arrangement is critical for their movement.

Conclude the relationship: Given the structural composition of cilia and flagella, microtubules are the cytoskeletal component responsible for their formation and function, distinguishing them from actin filaments and intermediate filaments.
