Mitosis + Meiosis

Question 1

Interphase

Answer 1

• cell growth and chromosomes replicate

Question 2

Mitosis

Answer 2

• division of the chromosomes
• maintains chromosomal number

Question 3

Prophase

Answer 3

• nuclear envelope breaks down
• chromosomes are condensed making them easier to move
• spindle is formed

Question 4

Prometaphase

Answer 4

• microtubules attach to sister chromatids from opposite poles

Question 5

Metaphase

Answer 5

• chromosomes align at the equator

Question 6

Anaphase

Answer 6

• sister chromatids separate
• chromosomes move to opposite poles

Question 7

Telophase

Answer 7

• nuclei reform and chromosomes decondense

Question 8

Cytokinesis

Answer 8

• membrane pinches to separate cytoplasm
• results in two diploid cells

Question 9

Meiosis

Answer 9

• two nuclear divisions
• produces four haploid daughter cells
• each daughter cell has half the number of chromosomes of the diploid parent cell

Question 10

Prophase I

Answer 10

• nuclear envelope breaks down
• chromosomes condense, crossing over occurs
• spindle fibers form

Question 11

Metaphase I

Answer 11

• homologous pairs align at equator

Question 12

Anaphase I

Answer 12

• homologous pairs separate and move to opposite poles

Question 13

Telophase I + Cytokinesis

Answer 13

• one set of paired chromosomes arrives at each pole
• cytoplasm divides

Question 14

Prophase II

Answer 14

• new spindle forms around the chromosomes

Question 15

Metaphase II

Answer 15

• chromosomes align at equator

Question 16

Anaphase II

Answer 16

• chromatids pulled to opposite poles

Question 17

Telophase II + Cytokinesis

Answer 17

• nuclear envelope forms around each set of chromosomes
• cytoplasm divides
