B)centrosome
C)plasma membrane
D)centromere
E)mitochondrial outer membrane

Question

Quizplus · Accepted Answer

The minus ends of microtubules are anchored at the centrosome, which is the main microtubule organizing center in animal cells. This ensures that the dynamics associated with microtubules occur at the plus ends, which grow and shrink in response to cellular signals and motor protein activity. The centriole is a substructure within the centrosome that helps to nucleate and organize microtubules, but it is not directly involved in anchoring the minus ends. The plasma membrane, centromere, and mitochondrial outer membrane are not typically involved in microtubule dynamics or organization.
