To begin with, the outside diameter of a microtubule (usually about 25 nm) is much greater than that of microfilaments. Furthermore, microtubules are hollow, containing a central lumen about 15 nm in diameter. …
WebThe main function of the centrosomes is to stimulate the production of and organize the distribution and orientation of microtubules in the cell. Microtubules play many functions in the cell, from giving it shape/structure to acting as a sort of “highway” for intracellular transport. As such, the action of the centrioles in creating and ...
