Detailed explanation-1: -Answer and Explanation: The paired rod-like structure constructed of microtubules at the center of each animal cell centrosome is called the centriole. Centrioles act as an organizing center for microtubules in the cell.

Detailed explanation-2: -Centrosomes are composed of a pair of centrioles buried in a complex pericentriolar matrix. The bulk of microtubules in cells lie with one end buried in the pericentriolar matrix and the other extending outward into the cytoplasm. Centrioles recruit and organize pericentriolar material.

Detailed explanation-3: -A bound pair of centrioles, surrounded by a highly ordered mass of dense material, called the pericentriolar material (PCM), makes up a structure called a centrosome.

Detailed explanation-4: -Centrosomes (1-17) Each of two centrosomes, the major microtubule organizing and nucleating centers in cells, consists of apair of centrioles (a mother centriole and a daughter centriole), surrounded by themicrotubule organizing center (MTOC).

Detailed explanation-5: -Centrioles are rod-shaped organelles. They are made up of 9 bundles, each of which has 3 microtubules. Centrosomes are made up of two perpendicularly positioned centrioles and their encircling proteins.
