Which organelle aids in cell division in animal cells only?

Explanation:
Centrioles organize the spindle that pulls chromosomes apart during animal cell division. They are part of the centrosome and help assemble the microtubules that form the mitotic spindle, guiding sister chromatids to opposite poles as mitosis proceeds. In plant cells, centrioles are not used to organize the spindle; instead, other microtubule organizing centers handle spindle formation, so centrioles are a feature commonly associated with animal cells. The other organelles—lysosomes (digestion), mitochondria (energy), and ribosomes (protein synthesis)—do essential cellular jobs but do not directly organize chromosome separation during division.
