Question

What are amorphous pericentriolar materials in contrast to centrosomes?

Answer 1

$\bold\pink{PERICENTRIOLAR\:MATERIALS}$

Pericentriolar material (PCM, sometimes also called pericentriolar matrix) is an amorphous mass of protein which makes up the part of the animal centrosome that surrounds the two centrioles. The PCM contains proteins responsible for microtubule nucleation and anchoring including γ-tubulin, pericentrin and ninein.

Answer 2

I would give an easy explanation for this answer:-

So basically, Pericentriolar Material is nothing except an amorphous mass of protein that makes up the part of the animal centrosome that surrounds the two centrioles (during mitosis cell division)

I hope that this answer will be helpful for you, dear. :)
