Slide 2 - Tekstslide

What are the three reasons why cells remain small?
A
Large cells have difficulty diffusing nutrients rapidly enough
B
As cells grow, their ratio of surface area to volume decreases
C
Transportation of wastes become a problem for larger cells

Mitosis
One cell will split in two exact copies

One mother cell will become 2 daughter cells.

Slide 8 - Tekstslide

Prophase
  • Chromosomes condense: each has two chromatids
  • Nuclear membrane starts breaking down
  • Spindle apparatus appears 

Slide 9 - Tekstslide

Metaphase
  • Centromeres lined up on the equator
  • Each chromatid attached to a spindle fibre 

Slide 10 - Tekstslide

Anaphase
  • Separation of the sister chromatids 
  • Sister chromatids move to opposite poles, now called chromosomes

Slide 11 - Tekstslide

Telophase
  • Chromosomes have reached poles
  • Nuclear membranes start forming
  • Chromosomes uncoil, become less visible 

Slide 12 - Tekstslide

Cytokinesis
  • Actual splitting of cytoplasm
