Mainly for teenagers but also for enquiring adults, the annual 2009 Royal Institution Christmas Lectures by  - Prof. Sue Hartley is about the evolutionary 300 million year battle between plants and herbivores (an animal that is adapted to eat plants). 

In the first lecture (available to play until 20 January 2010) random topics include:-

  • Trichromes 
    • fine outgrowths or appendages on plants eg hairs, glandular hairs, scales, and papillae
  • Dorset Naga Pepper
    • hottest chilli in the world
  • Bird's-foot Trefoil
  • Phytolith
    • silica to make plants distasteful, lending the plant's tissues a grainy or prickly texture.
  • Nettle
  • Ricin
    • Ricin is poisonous acting as a toxin by the inhibition of protein synthesis.
