a component of cytoskeleton, they're the framework for a cell.
a centriole.
The mitochondria generate energy in the form of ATP, which is used to power the movement of various cellular components along microtubules. Microtubules serve as tracks for transporting mitochondria to where they are needed in the cell, helping to distribute energy production throughout the cell efficiently. This interplay between mitochondria and microtubules ensures proper cellular function and organization.
