Final answer:
The statement that centrosomes are essential for cell division in animals is true. Centrosomes contain centrioles that aid in organizing chromosomes during division, ensuring proper chromosome segregation to daughter cells.
Step-by-step explanation:
Centrosomes, also called microtubule-organizing centers, are indeed crucial for cell division in animals, meaning the answer to the question is A) True. Centrosomes are found near the nucleus of animal cells and contain a pair of centrioles. Each centriole is a cylindrical structure composed of nine triplets of microtubules, and they lie perpendicular to each other. During cell division, centrosomes play a vital role in the formation of the mitotic spindle, which is essential for the proper separation of chromosomes into daughter cells.
Although the centrosome and centrioles are not fully understood, and there are cells that can divide without them, their presence helps to organize the chromosomes before cell division, ensuring that each daughter cell receives the correct number of chromosomes.
