Mitosis
Single cell makes 2 identical daughter cells
How many chromosomes do new cells from Mitosis have?
46
Mitosis use
Replacing damaged/worn out cells and for body growth
Meiosis
2 daughter cells divide to form unique gametes (4 daughter cells)
How many chromosomes are in Meiosis daughter cells?
23
Stem Cells
Unspecialised cells that can develop into other cells - divided via mitosis
Stem cells use
Used to grow tissue, organs - help with spinal injuries, Parkinson’s and T1D
Embryonic Stem Cells
From early embryo/ umbilical cord - readily available from IVF - moral issues
Meristem Stem Cells
Plant tissue, roots and shoots - Plants quickly and economically
Adult Stem Cell
Bone marrow from adult bones - only transforms into blood cells, no rejection, can cause infection
