Most of a plants cells can differentiate all throughout their lives 8 of 12 When do plant cells differentiate? When they are in their final position in the plant 9 of 12 How can some stem cells be used in medicine? They are able to grow into different types of required cells in patients, and so can imporve treatment dramatically 10 of 12 How can stem cells be used in terms of helping plants? They can make clones of plants from their meristems and this can be used to hep make more rare plants reliably and safely 11 of 12 Give examples of other uses of stem cells in medicine: Spinal cord after injuries, Diabetes, heart after damage in a heart attack, eyesight in the blind, damaged bone and cartilage 12 of 12
