Flashcards in Mitosis & Meiosis Deck (41):
1

Stages of mitosis

Interphase (3 parts- g1, S, g2), prophase, metaphase, anaphase, telophase and cytokinesis

2

Mitosis - Site of process

Somatic cells (body cells)

3

Meiosis- site of process

Gonad cells (sex cells)

4

Mitosis- are parents cells haploid or diploid?

Diploid

5

Meiosis- a parent cells diploid or haploid?

Diploid

6

Mitosis-Chromosome replication occurs

Interphase (synthesis)

7

Meiosis - chromosome replication occurs?

Interphase (synthesis)

8

Mitosis - line up in homologous pairs?

No

9

Meiosis- line up in homologous pairs?

Yes metaphase 1

10

Mitosis- spindle fibres pulp chromosomes apart?

Yes anaphase

11

Meiosis- spindle fibres pull chromosomes apart?

Yes anaphase 2

12

Mitosis- number of daughter cells?

2

13

Meiosis - number of daughter cells?

4

14

Mitosis- daughter cells are haploid or diploid?

Diploid

15

Meiosis - daughter cells are haploid or diploid?

Haploid

16

What are the two types of cell division?

Mitosis and meiosis

17

Where in interphase do the chromosomes replicate?

Synthesis

18

Stages of mitosis- interphase

G1,S,G2 chromosome replicate to have two chromatids

19

Stages of mitosis- prophase

Chromosomes and their chromatids become visible

20

Stages of mitosis- metaphase

Replicated chromosomes line up on the equator of the cells

21

Stages of mitosis- anaphase

the chromatids seperate and move to different sides of the cells

22

Stages of mitosis- telophase

Two nuclei form, both with the same number of chromosomes as the parent cell

23

Stages of mitosis- cytokinesis

Cell membranes form making two daughter cells, each with a nucleus

24

Stages of meiosis- metaphase 1

Replicated chromosomes form homologous pairs, attached to spindle fibres and line up in the middle

25

Stages of meiosis- anaphase 1

One replicated chromosome of each pair move to opposite poles

26

Stages of meiosis- telophase 1

Two cells are formed, each with one replicated chromosomes

27

Stages of meiosis- metaphase 2

Chromosomes line up on the equator attached to spindle fibres

28

Stages of meiosis- anaphase 2

Chromatids seperate and move to poles

29

Stages of meiosis- telophase 2

Four cells result with one copy of each chromosome, haploid gametes

30

Difference between haploid and diploid cells

Haploid cells have half the number of chromosomes as a diploid cells (N). Diploid cells contain a full set of chromosomes (2n).

31

What are gametes? Are they haploid or diploid?

They are the sex cells ( egg and sperm). They are haploid

32

What are somatic cells? Are they diploid or haploid cells?

Somatic cells are body cells. They are diploid.

33

Difference between mitosis and meiosis

Mitosis is the reproduction of body cells and there daughter cells contain a full set of chromosomes. Meiosis is the reproduction of gonad cells and there daughter cells are haploid cells

34

Define DNA replication

DNA replication is the copying of DNA resulting in two strands of DNA

35

Define chromatid

One of the strands of a chromosome after replication

36

Define mitosis

The cell division that produces two daughter cells identical to the parent cell

37

Define asexual reproduction

Is where the offspring produced using mitosis without any union of gametes

38

Define homologous chromosome

Chromosomes with genes for certain characteristics at the same location

39

Define meiosis

The type of cell division that produces cells with half the number of chromosomes as the parent cell

40

Define sexual reproduction

The production of new organisms by combing the genetic information of two organisms

41

Define gamete

A sex cell ( haploid) sperm and egg cell
