Verified step by step guidance

Understand the context of the question: During cell division, spindle fibers are responsible for separating chromosomes into daughter cells. The organelle that anchors these spindle fibers plays a critical role in this process.
Recall the function of the centrosome: The centrosome is an organelle found in animal cells that serves as the main microtubule-organizing center. It is responsible for forming and anchoring spindle fibers during mitosis and meiosis.
Eliminate incorrect options: The mitochondrion is involved in energy production, the lysosome is responsible for breaking down waste materials, and the Golgi apparatus is involved in modifying, sorting, and packaging proteins. None of these are involved in anchoring spindle fibers.
Focus on the centrosome: During cell division, the centrosome duplicates, and each centrosome moves to opposite poles of the cell. From these centrosomes, spindle fibers (microtubules) extend and attach to chromosomes to ensure proper segregation.
Conclude that the centrosome is the correct answer: Based on its role in organizing and anchoring spindle fibers, the centrosome is the organelle responsible for this function during cell division.
