Verified step by step guidance

Understand the process of eukaryotic cell division: Eukaryotic cell division involves the separation of chromosomes into two daughter cells. This process is called mitosis (or meiosis in the case of gametes). Key structures are required to ensure accurate chromosome segregation.
Identify the role of the spindle apparatus: The spindle apparatus is a structure made of microtubules that forms during cell division. It is directly responsible for attaching to chromosomes at their centromeres via kinetochores and pulling them apart to opposite poles of the cell.
Eliminate unrelated structures: The Golgi apparatus is involved in packaging and transport of proteins, the ribosome is responsible for protein synthesis, and the lysosome is involved in breaking down cellular waste. None of these are directly involved in chromosome segregation during cell division.
Focus on the spindle apparatus: The spindle apparatus is essential for ensuring that each daughter cell receives the correct number of chromosomes. It assembles during prophase and metaphase, aligns chromosomes at the metaphase plate, and separates them during anaphase.
Conclude that the spindle apparatus is the correct structure directly involved in eukaryotic cell division, as it plays a critical role in the accurate segregation of chromosomes.
