The structure in an animal cell that helps to organize cell division is called the centrosome.
The centrosome is a specialized area in the cell that contains a pair of centrioles, which are cylindrical structures made of microtubules. During cell division, the centrosome plays a crucial role in organizing the spindle fibers that separate the chromosomes. As the cell prepares to divide, the centrosome duplicates, and the two centrosomes move to opposite ends of the cell, forming the spindle apparatus that ensures the chromosomes are evenly divided between the daughter cells.
