Which structure is described as a microtubule that helps organize cell division?

Explanation:
During cell division, microtubules build the spindle that pulls chromosomes apart. Centrioles are cylindrical structures made of microtubules that organize this spindle by serving as the main organizing centers in many animal cells. They help organize the microtubule network at the centrosome so spindle fibers can attach to chromosomes and drive their movement apart. The other options don’t organize the spindle: ribosomes synthesize proteins, mitochondria provide energy, and chloroplasts carry out photosynthesis.
