Detailed explanation-1: -Microtubules are the thickest of the cytoskeletal fibers. These are hollow tubes that can dissolve and reform quickly. Microtubules guide organelle movement and are the structures that pull chromosomes to their poles during cell division. They are also the structural components of flagella and cilia.
Detailed explanation-2: -Microtubules. Despite the “micro” in their name, microtubules are the largest of the three types of cytoskeletal fibers, with a diameter of about 25 nm.
Detailed explanation-3: -The thickest and strongest fibers of the cytoskeleton are the microtubules. The microtubule is composed the protein tubulin, which comes in alpha and beta form. Alpa and beta tubulin are globular proteins that combine to form a hollow tube-like structure.
Detailed explanation-4: -Answer and Explanation: Out of the three main kinds of fibres making up the cytoskeleton of a eukaryotic cell, the thickest ones are the microtubules. The diameter of microtubules is approximately 25 nanometers. The diameter of microfilaments is 7 nanometers, and 8 to 12 nanometers for intermediate filaments.
