Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.icrotubules form a framework for structures such as the spindle apparatus that appears during cell division, or the whiplike organelles known as cilia and flagella. Cilia and flagella are the most well-studied models for microtubule structure and assembly, and are often used by textbooks to introduce microtubules.
Lesson Summary. The mitotic spindle is a structure composed of microtubules which segregates chromosomes into the daughter cells during mitosis. A microtubule is a rope-like component of the cytoskeleton. The centrosome is an organelle that serves as a microtubule organizing center during cell division.he centrosome is an organelle that serves as a microtubule organizing center during division. It's duplicated during S phase, and the two copies move to opposite sides of the cell. Now, once the mitotic spindle has been assembled, the centrosomes are also referred to as spindle poles.
