A scientist observes the motion of a certain type of vesicle around the cell. She notices that vesicle movement ceases when colchicine is added to the culture medium. What conclusion can she draw?

colchicine inhibits microtubule function, it is most likely that the

vesicular movement is orchestrated or produce by microtubules.

Explanation:

Microtubules is organelle in the cell which give shape to the cell and help transport vessicles, granules and some organelles inside the cell.

Colchicine is a chemical substance that inhibit microtubules function and for gout treatment.

When colchicine is added to the microtubules, vessicles movement is produce by microtubules.
