an undifferentiated cell of an organism which is capable of giving rise to many more cells of the same type, and from which certain other cells can arise from differentiation
1 of 11
describe the function of stem cells in embryos
stem cells from human embryos can be cloned and made to differentiate into most different types of human cells
2 of 11
describe the function of stem cells in adult animals
stem cells from adult bone marrow can form many types of cells found in blood including blood cells
3 of 11
describe the function of stem cells in meristems in plants
meristem tissue in plants can differentiate into any type of plant cell, throughout the life of the plant
4 of 11
give two conditions that could be helped by treatment with stem cells
diabetes and paralysis
5 of 11
what happens in therapeutic cloning
an embryo is produced with the same genes as the patient. stem cells from the embryo are not rejected by patients body so they may be used for medical treatment
6 of 11
what are the risks of using stem cells
viral infections can be transferred and some people have ethical or religious objections.
