microtubules

Microtubules are tiny, tube-like structures found in cells, playing a crucial role in maintaining their shape and organization. They are part of the cytoskeleton, which provides support and facilitates movement within the cell. Microtubules are made up of protein subunits called tubulin and are involved in processes such as cell division, where they help pull chromosomes apart, and intracellular transport, where they act like tracks for transporting materials. Their dynamic nature allows them to grow and shrink, adapting to the cell’s needs and functions.
