Question

Quizplus · Accepted Answer

Microtubules are hollow, filamentous structures composed of tubulin. They play a variety of roles in the cell, including providing structural support, assisting in cell division, and aiding in intracellular transport. They are not composed of myosin and do not interact with filaments to produce muscle contractions, nor are they involved in attaching the plasma membrane to the cytoplasm. They are also not found on ribosomes.
