Verified step by step guidance

Understand the context of cell division: Cell division is a process where a parent cell divides into two or more daughter cells. It is crucial for growth, repair, and reproduction in organisms.

Identify the role of spindle fibers: Spindle fibers are structures that form during cell division, specifically during mitosis and meiosis. They are composed of microtubules and are essential for the movement of chromosomes.

Explore the function of spindle fibers: During cell division, spindle fibers attach to the centromeres of chromosomes. Their primary purpose is to separate sister chromatids (or homologous chromosomes during meiosis) and ensure they are evenly distributed to the daughter cells.

Clarify the incorrect options: The spindle fibers do not provide energy for cell division, form the nuclear envelope, or replicate DNA. These functions are carried out by other cellular components and processes.

Conclude with the correct purpose: The primary purpose of spindle fibers is to ensure accurate segregation of chromosomes, which is vital for maintaining genetic stability across generations.
