The organelle that coordinates the movement of chromosomes during mitosis in animal cells is the centrosome. The centrosome serves as the main microtubule organizing center, producing spindle fibers that attach to chromosomes at their kinetochores. These spindle fibers help align and separate the chromosomes, ensuring their proper distribution into the daughter cells.
The organelle responsible for forming spindle fibers during cell division is the centrosome. The centrosome is composed of two centrioles and plays a critical role in organizing and anchoring the spindle fibers that help separate the chromosomes during mitosis.
The area near the nucleus that is made of two centrioles is the centrosome. Centrioles play a key role in cell division by organizing the spindle fibers that separate the chromosomes during mitosis.
Spindle fibers originate from structures called centrosomes, which are located at opposite poles of the cell during cell division. Each centrosome contains a pair of centrioles that help organize microtubules, forming the mitotic spindle. The spindle fibers are primarily composed of microtubules, which extend and attach to chromosomes at their kinetochores to facilitate their movement during mitosis.
The fibers, known as spindle fibers, appear during prophase of mitosis. They begin to form as the centrosomes move to opposite poles of the cell, and the microtubules extend from the centrosomes. These fibers attach to the chromosomes at their kinetochores during prometaphase, facilitating their alignment and separation in subsequent stages.

The cables made of microtubules that extend from the poles of a cell to the centromeres during cell division are called spindle fibers or mitotic spindles. They help in the separation of chromosomes during mitosis or meiosis by attaching to the centromeres.
The centrosome, made up of two centrioles, plays a crucial role in organizing the mitotic spindle during cell division. The centrosomes move to opposite ends of the cell and serve as the poles for the spindle fibers to attach and pull the chromosomes apart during mitosis.
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.

Centrioles. They are visible during metaphase, the second stage of mitosis. Added: Centrosomes. Centrioles are present in animal cells but are, seemingly, not needed to mount a spindle apparatus. Plant cells get along very well without centrioles.
