Verified step by step guidance
1
Understand the structure of eukaryotic cilia and flagella: They are hair-like structures that protrude from the surface of eukaryotic cells and are involved in movement and sensory functions.
Identify the main structural component of eukaryotic cilia and flagella: They are primarily composed of microtubules, which are cylindrical structures made of tubulin proteins.
Differentiate between the options given: Intermediate filaments, chitin, phospholipids, and cellulose are not the primary components of cilia and flagella.
Recall the arrangement of microtubules in cilia and flagella: They typically have a '9+2' arrangement, where nine pairs of microtubules form a ring around two central microtubules.
Conclude that microtubules are the correct answer, as they provide the structural framework and are essential for the movement of cilia and flagella.
