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
