Chapter 10 Cell Division

Question 1

Two Main Stages of The Cell Cycle

Answer 1

1. Interphase (most cells spend 90% of lifespan here)
2. Cell Division (Mitosis and cytokinesis)

Question 2

Mitosis Characteristics

Answer 2

Cell Division of Somatic Cells (all cells besides sex cells)

Asexual Reproduction (keep same number of chromosomes in original & duplicate)

ONE DIVISION

Sister Chromatids Separate

Question 3

5 Stages of Mitosis

Answer 3

Prophase

Prometaphase (extremely fast)

Metaphase

Anaphase

Telophase

Cytokinesis: division of the cytoplasm

Question 4

Prophase (hints Poles)

Answer 4

Cell enters mitosis

• Chromosomes Condense
• Centrosomes move apart (go to the poles of the cell)
• Mitotic spindle begins to form

Question 5

Prometaphase

Answer 5

• mitosis proceeds
  
  • chromosome condensation completed
  • nuclear envelope breaks down
  • mitotic SPINDLE extends from centrosomes

Question 6

Metaphase (hint they met)

Answer 6

• Chromosomes Line Up
  
  • metaphase plate
  • align sister chromatids
    
    • equal and balanced
    • segregation

Question 7

Anaphase (hint AWAY)

Answer 7

• Chromatids separate
  
  • break free and dragged to opposite sides
• Microtubules shorten
• Result: equal segregation of chromosomes in two daughter cells
