MICROTUBULE TRACKWAYS

How do materials move about in living cells? Amazingly there is a "rapid transit system" composed of microtubule (the tracks) and carrier molecules (the trucks) that tote supplies (often contained in vesicles) from manufacturing sites, out to where they are needed. Microtubules also pull and push cell structures such as chromosomes and act as structural elements in cells.
