During cell division, structures like the chromosomes, spindle fibers, and centrioles are more clearly visible. Chromosomes condense and can be seen as distinct entities, spindle fibers form a dynamic network between the centrioles, and the centrioles organize the spindle apparatus.
Spindle fibers. These structures form the mitotic spindle and play a crucial role in separating chromosomes during cell division.
Mitotic spindle fibers are microtubule structures that form during cell division to help separate duplicated chromosomes into two daughter cells. They aid in the precise distribution of genetic material by attaching to and moving chromosomes to opposite ends of the cell.
1 Prophase - DNA coils up , chromatids form and chromosomes become visible, nuclear envelope dissolves, and spindle fibers form.

During cell division, structures like the chromosomes, spindle fibers, and centrioles are more clearly visible. Chromosomes condense and can be seen as distinct entities, spindle fibers form a dynamic network between the centrioles, and the centrioles organize the spindle apparatus.
The fibers that form around centrioles during cell division in animal cells are called spindle fibers. These fibers are crucial for separating chromosomes and ensuring each daughter cell receives the proper number of chromosomes during mitosis.
Spindle fibers. These structures form the mitotic spindle and play a crucial role in separating chromosomes during cell division.

Mitotic spindle fibers are microtubule structures that form during cell division to help separate duplicated chromosomes into two daughter cells. They aid in the precise distribution of genetic material by attaching to and moving chromosomes to opposite ends of the cell.
The centriole is the structure responsible for producing microtubule fibers needed for organizing and separating chromosomes during cell division. These fibers form the spindle apparatus, which helps in the distribution of chromosomes to daughter cells during both mitosis and meiosis.
1 Prophase - DNA coils up , chromatids form and chromosomes become visible, nuclear envelope dissolves, and spindle fibers form.
Interphase - As the cell prepares for mitosis, the chromosomes replicate during the S phase of interphase.Prophase - The replicated chromatids begin to coil into recognizable chromosomes; the nuclear membrane fragments; centrioles move to form the cell's poles; spindle fibers form; nucleolus disintegrates.Metaphase - Chromosomes attach to spindle fibers at their centromeres and then move to the equator.Anaphase - Chromatids, now called daughter chromosomes, separate toward the poles.Telophase - The nuclear membranes and nucleoli re-form; spindle fibers fragment; the chromosomes unwind and change from chromosomes to chromatin.Daughter Cells: Cytokinesis occurs and twoRead more: What_is_happening_on_each_stages_of_mitosis
chromatids
The structure is called a chromosome. Chromosomes are visible during cell division as they condense to form distinct, visible structures that contain tightly coiled DNA.
Prophase is the first stage of mitosis where the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle fibers begin to form.
Chromosomes' centromeres are indeed attached to kinetochore fibers, which are essential for proper chromosome movement during cell division. These fibers help align the chromosomes at the center of the cell and then pull them apart into separate daughter cells during mitosis. The kinetochore is a specialized protein structure located at the centromere that serves as the attachment point for the kinetochore fibers.
