stem cells

• Therapeutic cloning

  Producing an embryo with the same genes as the patient to obtain stem cells for treatment
• Benefits and problems of stem cell research

  • Benefits: Can replace damaged/diseased body parts, use unwanted embryos, research differentiation
  • Problems: Don't fully understand differentiation, destroying embryos, ethical concerns, risk of contamination, money could be better spent
• stem cell

  An undifferentiated cell that can divide to make more stem cells or differentiate into certain types of cells
• Stem cells from human embryos can differentiate into most types of cell.

  Stem cells from adults can only differentiate into certain cell types.
• Plant stem cells are found in

  meristem tissue at the growing tips of shoots and roots
• Plant stem cells can differentiate throughout the life of a plant
