How are plant stem cells different to human stem cells?
Human stem cells can become any kind of human cell, plant stem cells can only become root cells or leaf cells.
Human stem cells can only become neurones or kidney cells, whereas plant stem cells can become any kind of cell.
Once plant cells have differentiated into specialised cells, they can re-differentiate into another type of specialised cell if needed.
Once human cells have differentiated, they mutate to give you special powers, like x-ray vision!
