What Is An Analogy For Microtubules?
Microtubules have two main functions in cells and in doing so act like a skeleton as well as like railroadtracks. Microtubules are the main structural component of the cytoskeleton in cells, which provides the cell with structure and rigidity and determines the shape of the cell. They also serve to transport vesicles and proteinswithin the cytoplasm through transport proteins called kinesins and dyneins, which act much like railroad cars.
