HST-AP - Mitosis/Cell Division

The video explains how cells reproduce through mitosis, an asexual process where a single cell divides into two identical cells. It highlights that not all body cells reproduce at the same rate, with some, like heart and nerve cells, not reproducing after damage. The process of mitosis is likened to a play, with various cell components acting as cast members. The video details the stages of mitosis, including the roles of the nucleus, chromatin, chromosomes, chromatids, centrioles, centrosome, spindle fibers, and centromeres. A review of these components concludes the video.

Which type of cells reproduce constantly?

• Muscle cells

• Skin cells

• Cardiac muscle cells

• Brain cells

What is the role of the nucleus in mitosis?

• It disappears during cell division.

• It organizes chromatin into chromosomes.

• It forms spindle fibers.

• It splits the cytoplasm.

What do chromosomes become after they duplicate?

• Chromatin

• Spindle fibers

• Centromeres

• Chromatids

What is the function of spindle fibers during mitosis?

• To duplicate the centrioles

• To form the cell membrane

• To attach to centromeres and separate chromatids

• To condense DNA into chromosomes

What happens to the chromatids during the 'tug of war' phase?

• They become chromatin.

• They are pulled apart to opposite ends of the cell.

• They line up in the center of the cell.

• They duplicate again.

Which structure connects sister chromatids together?

• Centrosome

• Cytoplasm

• Centromere

• Nucleus

What is the final result of mitosis?

• Two identical cells

• Four different cells

• One larger cell

• No change in the cell
