stem cells

• Stem Cells

  Can turn into ANY type of cell
• Stem cells

  1. Can be grown in a lab to produce

  2. May be able to cure many diseases

  3. May be able to replace damaged cells in sick people
• Potential uses of stem cells in medicine

  • Cure diseases
  • Replace damaged cells in sick people
• Some people are against stem cell research


  Because they believe human embryos used in research are potential human lives
• Campaigns for the rights of embryos


  Want to ban stem cell research using embryos
• Stem cell research is allowed in the UK as long as it follows regulations
• Stem Cells in plants

  • Can produce identical plants
  • Found in the meristems (parts of the plant where growth occurs)
  • Cells in the meristem tissues can differentiate into any cell type
  • Can be used to produce clones (identical copies) of whole plants quickly and cheaply
  • Can be used to grow more plants of rare species to prevent them being wiped out
  • Can be used to grow crops of identical plants with desired features
• Florists use stem cells, and nobody complains about that
• Cell Membrane


  • They're clever
  • Detect substances
  • Only very selectively allow things like nutrients and gases to pass through
  • Big mouths to take in nutrients
  • Just like with humans, they're one of the most important parts of the cell
  • The larger the surface area, the more efficiently they can carry out their functions
