Microtubules are essential components of the cell's cytoskeleton, forming dynamic hollow tubes that provide structural support and enable critical processes like intracellular transport and cell division. Composed of tubulin dimers, these structures allow motor proteins to move organelles and vesicles efficiently throughout the cytoplasm, maintaining cellular organization and function.
