During cell division, specifically in mitosis, a structure known as the spindle apparatus forms between the poles. This spindle is composed of microtubules that extend from the centrosomes, which are located at opposite ends (poles) of the cell. The spindle helps to align and separate the chromosomes, ensuring that each daughter cell receives an equal and accurate distribution of genetic material.
the spindle
Fibrils operate during cell division and guide the chromosomes during meiosis and mitosis to their respective poles, ensuring even division of DNA.
A biorientation is an orientation of chromosomes to opposite poles of the bipolar spindle before cell division.
The phase occurring when chromatids are separated and a visible line forms between sets of chromatids is called anaphase. During anaphase, the sister chromatids are pulled apart toward opposite poles of the cell by the spindle fibers. This separation ensures that each new daughter cell will receive an identical set of chromosomes during cell division. The formation of the visible line indicates the cleavage furrow beginning to form as the cell prepares for cytokinesis.
Telophase is the final stage of cell division during which the separated chromosomes reach opposite poles of the cell and a new nuclear membrane forms around each set of chromosomes. This is followed by cytokinesis, where the cell divides into two daughter cells.

The two Poles of a cell that migrate during cell division are the centrosomes, which are the microtubule organizing centers located at opposite ends of the cell. These centrosomes help to organize and separate the chromosomes during cell division, ensuring each daughter cell receives the correct number of chromosomes.
Cell division forms multiple cells, which of course forms your body. So cell division is the making of new cells. Hope it helps a lot! :)
The opposite ends of a cell are called the poles. These poles play a key role in cell division and directionality of cellular processes.
spindle fibers
spindle fibers
Spindle fibers are responsible for separating sister chromatids during cell division by attaching to and helping to move the chromosomes to opposite poles of the cell. They help ensure that each daughter cell receives the correct number of chromosomes.
There are not many differences between animal and plant cell division, only that when it comes time for the cell to divide during cytokinesis, the plant cell grows a cell plate in between the two nuclei, and the animal cell forms a cleavage furrow (like the cell is being pinched) and divides.
The division cell plate appears during the telophase stage of cell division, specifically in cytokinesis. It forms in between the two new daughter cells as the cell membrane pinches inward to separate them.
fibers
They are called poles, for example in anaphase chromosomes are pulled to the opposite poles of the cell.
