DNA, gene, chromosome, nucleus, cell
3 stages of the cell cycle
interphase, mitosis, cytokinesis
three things that happen during interphase 
1)The Cell grows 2) chromosomes are copied 3)more mitochondria and ribosomes are made
what happens during mitosis 
chromosomes pulled to opposite ends of the cell
what happens during cytokinesis
cell membrane and cytoplasm split in two
why the cell cycle is important  
more cells are made for growth and repair
what is produced in the cell cycle
two genetically identical daughter cells
mitosis produces which type of cell  
diploid cells
define stem cells
an undifferentiated cell
3 Places where stem cells can be found in humans
Embryos, adult bone marrow, meristem
two conditions that stem cells can be used to treat in humans
paralysis and type 1 diabetes
two uses of stem cells in plants 
1)clone rare species 2)produces diseases resistance crops
what is meant by "therapeutic cloning" 
using clones of a patient's own stem cells to treat them
which cells are required for "therapeutic cloning"
egg cell and a normal body cell from patient
two objections to using stem cells in treatment
potential transfer of viral infections and ethical/religious objections
