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
D
All of the above

Interphase
- Cell spends most of it's time 
in interphase
-cell grows and does normal
 cell functions
-prepares for cell division 
by copying it's DNA

Slide 6 - Slide

Mitosis
One cell will split in two exact copies

One mother cell will become 2 daughter cells.

Slide 7 - Slide

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

Slide 8 - Slide

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

Slide 9 - Slide

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

Slide 10 - Slide

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

Slide 11 - Slide

Cytokinesis
  • Actual splitting of cytoplasm
