1.2 Cell Division
Stem Cells
An unspecialised cell that is capable of differentiating into other cell types and of self- renewal
Plant Cells
Meristem Cells
Can differentiate into any kind of plant cell during the plant’s life
Animal Cells
Embryonic Stem Cells
Can differentiate into most types of human cells
Bone marrow stem cells
Can differentiate into some types of cell e.g. blood cells
Treatment
e.g. diabetes, paralysis
Embryo cloned with the same genetic makeup as the patient → no rejection
Cell Cycle
Interphase
Cell grows in size, synthesises new organelles
DNA replicates
Mitosis
2 sets of chromosomes
Separated to opposite poles of the cell
Produces two genetically identical cells
For growth and repair
Cytoplasm Division
Therapeutic Cloning
Embryo cloned with the same genetic makeup as the patient → no rejection
Protection of rare species from extinction
Plant meristem cloning
Enables production of large numbers of disease-resistant plants
Chromosomes
DNA molecules combined with proteins
Humans have 46 chromosomes (23 pairs)
Carry genes
A section of DNA which codes for a protein
