Cell division - Part 2: Mitosis

Question 1

prophase

Answer 1

• chromosomes condense in the middle of the cell
• centrosomes migrate to opposite ends of the cell

Question 2

metaphase

Answer 2

• chromosomes line up in the middle

Question 3

anaphase

Answer 3

• sister chromatids separate and migrate to opposite ends of the cell

Question 4

prometaphase

Answer 4

• spindles attach to chromosomes
• nuclear envelope breaks down

Question 5

kinetochores

Answer 5

• associate with the centromere and form an attachment to the microtubules of the mitotic spindle
• oppose each other (bi-orientation)

Question 6

telophase

Answer 6

• nuclear envelope reforms
• chromosomes decondense

Question 7

cytokinesis (animal)

Answer 7

• cytoplasm divides
• contractile ring bisects the cell

Question 8

cytokinesis (plant)

Answer 8

• formation of a new cell wall that separates daughter cells
