Cell division

Question 1

Mitosis

Answer 1

A cell division process that results in new genetically identical cells with the same number of chromosomes as the original cell.
- Asexual reproduction
- Occurs in somatic/non-reproductive cells.

Question 2

Interphase

Answer 2

• Chromosomes/DNA replicates
• Normal cell activities

Question 3

Prophase

Answer 3

• Nuclear membrane disappears.
• Chromosomes become visible.

Question 4

Metaphase

Answer 4

Chromosomes align at middle.

Question 5

Anaphase

Answer 5

Chromatids separate

Question 6

Telophase

Answer 6

2 nuclei form

Question 7

Cytokinesis

Answer 7

• Cell splits into two.
• Result = 2 identical diploid daughter cells.

Question 8

Meiosis

Answer 8

A cell division process that results in new cells with half the number of chromosomes as the original cell.
- Sexual reproduction.
- Occurs in sperm/egg cells (reproductive cells).

Question 9

Prophase I

Answer 9

• Chromosomes condense
• Homologous pairs match up.

Question 10

Metaphase I

Answer 10

Chromosomes line up in homologous pairs.

Question 11

Anaphase I

Answer 11

Homologous pairs separate.

Question 12

Telophase I

Answer 12

2 nuclei form.

Question 13

Cytokinesis I

Answer 13

Cell splits into two.

Question 14

Prophase II

Answer 14

Chromosomes condense

Question 15

Metaphase II

Answer 15

Chromosomes line up in the middle.

Question 16

Anaphase II

Answer 16

Chromatids separate.

Question 17

Telophase II

Answer 17

2 nuclei form.

Question 18

Cytokinesis II

Answer 18

• Cells splits into 4.
• Result = 4 haploid daughter cells.

Question 19

Mitosis only

Answer 19

• Results in identical cells with same number of chromosomes as parent.
• Asexual reproduction.
• Result = diploid.
• Occurs = somatic cells.
• Produces 2 daughter cells.

Question 20

Mitosis + meiosis (both)

Answer 20

• Results in new cells.
• Starts with a parent cell.
• Result = at least 1 daughter cell.

Question 21

Meiosis only

Answer 21

• Where crossing over and independent assortment occurs.
• Result = cells with half the number of chromosomes as parent cell.
• Occurs = gametes.
• Result = haploid cells.
• Produces 4 daughter cells.

Question 22

Diploid

Answer 22

2 copies of each chromosome (2n).

Question 23

Haploid

Answer 23

1 copy of each chromosome (n).

Question 24

Homologous

Answer 24

Pair (1 from mum, 1 from dad).

Question 25

Chromatid

Answer 25

Identical half of a replicated chromosome.
