Intracellular vesicles can move across a cell quickly, indicating that the mechanism of vesicle movement is most likely not a function of passive diffusion through the cytoplasm. which of the following best describes the mechanism through which vesicles move throughout a cell? vesicles slide along the microtubules of the cytoskeleton. vesicles are propelled through the cytoplasm by small structures similar to flagella. vesicles have an osmotic pump that forces small amounts of cytoplasm out in one direction as it contracts, pushing the vesicle forward in the opposite direction. vesicles are moved throughout the cytoplasm by atp-driven transport prions.
