Cell division
Cell division is happening constantly in your body:
  • 3,5 kg of new skincells every year
  • 200.000.000.000 new bloodcells every day
Cells also die a lot!
  • More new cells than dead cells > growth

Slide 6 - Slide

Cell cycle

Slide 7 - Slide

Slide 8 - Video

Cell cycle
  • 1 daughter cell > specialised cell > heartcell, musclecell, bloodcell, etc.
  • 1 daughter cell > stem cell > parent cell
  • Stem cells can divide into new cells
  • Stem cells don't specialise,
    but they're responsible for growth
    and for the recovery of the body 
    tissues
  • Bone marrow: fat cell/bone cell/
    blood cell
skin cells
nerve cell
blood cells
embryonic stem cell

Slide 9 - Slide

A human stem cell divides.
The daughtercells are called cell A and cell B.
How many chromosomes are in cell A? (only use numbers)

Slide 10 - Open question

Cell A is a stem cell.
Cell A divides into cell B and C.
Cell B becomes a liver cell.
What happens with cell C?
A
Becomes a liver cell
B
Becomes a body cell
C
Becomes a stem cell
D
Impossible to tell
