Cell Division

• What are the 3 stages of the cell cycle?

  Mitosis

  Interphase

  Cytokinesis
• What is the ROLE of MITOSIS and THE CELL CYCLE?

  To produce identical daughter cells for growth and asexual reproduction.
• What does mitosis not give rise to?

  genetic variation
• Why does mitosis not give rise to genetic variation?

  Because all cells produced by mitosis are genetically identical
• What is mitosis a form of ?

  cell division
• What does mitosis produce?

  identical cells
• how many stages of mitosis are there?

  4
• what are the four stages of mitosis?

  prophase

  metaphase

  anaphase

  telophase
• What takes place during INTERPHASE?

  During this stage the cell grows and then prepares to divide - chromosomes and some organelles are replicated, chromosomes also begin to condense
• What happens during cytokinesis?

  During cytokinesis the parent and replicated organelles move to opposite sides of the cell and the cytoplasm divides thus producing two daughter cells
• Why is mitosis important?

  growth

  repair

  reproduction
• Why is mitosis important for GROWTH?

  All cells produced are identical so organisms can grow using mitosis
• Why is mitosis important for REPAIR?

  All cells produced are identical so organisms can replace dead tissues using mitosis
• Why is mitosis important for REPRODUCTION?

  Some single-celled organisms , like yeast, reproduce by dividing into two identical daughter cells by mitosis
• What does meiosis produce?

  4 daughter cells each with half the number of chromosomes as the parent cell
• How many daughter cells does meiosis produce?

  four
• What does mitosis produce?

  2 daughter cells, with the same number of chromosomes as the parent cell
• How many daughter cells does mitosis produce?

  2
• What is the cell not doing during interphase?


  dividing
• is the cell dividing during interphase?

  no
• Replication of what occurs during interphase?

  replication of DNA
• What are the 3 phases of interphase?
