Final answer:
Microtubules are longer, thicker, and organized near the centrosome at the nucleus.
Step-by-step explanation:
The microtubules are longer, thicker, and organized near the centrosome at the nucleus. Microtubules are hollow cylinders made of polymers of alpha and beta tubulin and radiate outwards from the centrosome. They help maintain cell shape, hold organelles in place, and form the mitotic spindle during cell division.
