Mitosis and Meiosis

Question 1

Number of divisions

Answer 1

Mitosis: 1
Meiosis:2

Question 2

Number of cells at the end

Answer 2

Mitosis: 2
Meiosis:4

Question 3

Chromosome count

Answer 3

Mitosis: Same
Meiosis: half

Question 4

Steps

Answer 4

Mitosis:Prophase, Metaphase, Anaphase, Telophase.
Meiosis: (Meiosis 1) Prophase I, Metaphase I, Anaphase I, Telophase I; (Meiosis 2) Prophase II, Metaphase II, Anaphase II and Telophase II.

Question 5

What does it create

Answer 5

Mitosis: Makes everything but sex cells
Meiosis: Only sex cells

Question 6

Type of reproduction

Answer 6

Mitosis: Asexual
Meiosis: Sexual

Question 7

What is prophase ( Mitosis )

Answer 7

Prophase occupies over half of mitosis. The nuclear membrane breaks down to form a number of small vesicles and the nucleolus disintegrates.

Question 8

What is prometaphase (Mitosis)

Answer 8

The chromosomes, led by their centromeres, migrate to the equatorial plane in the mid-line of the cell - at right-angles to the axis formed by the centrosomes.

Question 9

Metaphase (Mitosis)

Answer 9

The chromosomes align themselves

Question 10

Anaphase ( Mitosis )

Answer 10

The centromeres divide, and the sister chromatids of each chromosome are pulled apart -

Question 11

Telophase ( Mitosis )

Answer 11

The final stage of mitosis, and a reversal of many of the processes observed during prophase. The nuclear membrane reforms around the chromosomes grouped at either pole of the cell, the chromosomes uncoil and become diffuse, and the spindle fibres disappear.

Question 12

Cytokinisis ( Mitosis )

Answer 12

The final stage in Mitosis where there are two separate cells

Question 13

Prophase 1 ( Meiosis)

Answer 13

The homologous chromosomes pair and exchange DNA to form separated chromosomes

Question 14

Prometaphase 1 (Meiosis)

Answer 14

Spindle apparatus formed, and chromosomes attached to spindle fibres

Question 15

Metaphase 1 (Meiosis)

Answer 15

Chromosones arranged as doubles.

Question 16

Anaphase 1 ( Meiosis)

Answer 16

chromosomes are separated and move to the opposite poles of the cell

Question 17

Telophase 1 ( Meiosis)

Answer 17

Nuclear membrane re forms

Question 18

Cytokinesis (Meiosis)

Answer 18

The final cellular division to form two new cells, followed by Meiosis II. Meiosis I is a division: the original cell had two copies of each chromosome; the newly formed cells have one copy of each chromosome.
