DTo start cell division
Answer:
B. Spindle
Read Explanation:
Centrioles are small cylindrical structures found in animal cells, composed of microtubules.
They play an essential role in cell division, specifically the formation of the spindle apparatus.
This is the structure responsible for the separation and sharing of duplicated chromosomes to two daughter cells.
Its complexity is made possible through centrioles working as organizing centers, duplicating themselves before cell division and moving to opposite ends of the cell.
There, they connect with spindle fibers which attach to the replicated chromosomes and help pull them apart.
Thus, centrioles are indispensable for ensuring that genetic material is accurately distributed during mitosis and meiosis processes.
