Quizplus · Accepted Answer

Polar microtubules attach to the centrosomes but not the chromosomes and interdigitate with microtubules from the opposite pole, providing stability and separation of the two poles during cell division. Kinetochore microtubules attach to the chromosomes and pull them towards the poles, while astral microtubules radiate outwards from the centrosome and play a role in positioning the spindle during cell division. Interdigitating microtubules is not a commonly used term in the context of microtubule organization during cell division.
