Mitosis vs Meiosis

Slide 1 - Tekstslide

Learning objectives
  • Recognise whether a cell is undergoing mitosis or meiosis
  • Analyse and predict chromosome numbers and DNA amounts 

Slide 2 - Tekstslide

The picture depicts what phase of meiosis
A
Prophase 1
B
Prophase 2
C
Anaphase 1
D
Anaphase 2

Slide 3 - Quizvraag

Meiosis is a type of cell division that produces:
A
zygotes
B
diploid cells
C
hair cells
D
gametes

Slide 4 - Quizvraag

Which of the following distinguishes prophase 1 of meiosis from prophase of mitosis?
A
homologous chromosomes pair up
B
spindle forms
C
nuclear membrane breaks down
D
chromosomes become visible

Slide 5 - Quizvraag

A cell with a diploid number of 24 undergoes meiosis, how many chromosomes are in each daughter cell?
A
6
B
12
C
24
D
48

Slide 6 - Quizvraag

2n= 4 for this species. Which phase does this show?
A
Mitosis - Telophase
B
Mitosis- Anaphase
C
Meiosis - Telophase 2
D
Meiosis - Anaphase 2

Slide 7 - Quizvraag

2n= 8 for this species. Which phase does this show?
A
Mitosis - Telophase
B
Mitosis- Anaphase
C
Meiosis - Telophase 2
D
Meiosis - Anaphase 2

Slide 8 - Quizvraag

Cancer
  • Uncontrolled cell division
  • Mutations in genes that control mitosis: increase mitosis or not limit mitosis 
  • Result: more cells than necessary --> tumour
  • Carcinogens: increase chance of these mutations

Slide 9 - Tekstslide

Types of tumours
  • Benign: grows in a ball, stays together, does NOT spread
  • Malignant: grows faster, spreads out, metastasis

  • Metastasis: cell breaking off from
    primary tumour, travelling through body
    and forming secondary tumours

Slide 10 - Tekstslide

If a diploid organism has a genome consisting of 22 chromosomes, its gametes will have
_____ chromosomes.
A
44
B
11
C
22
D
88

Slide 11 - Quizvraag

At which stage of meiosis do chromatids separate and become daughter chromosomes?
A
Metaphase 1
B
Metaphase 2
C
Anaphase 1
D
Anaphase 2

Slide 12 - Quizvraag

Meiosis II is similar to mitosis in that...
A
homologous chromosomes group together
B
the daughter cells are diploid
C
sister chromatids separate during anaphase
D
the chromosome number is reduced

Slide 13 - Quizvraag
