  1. Secondary metabolites Not found in all plants Dyes, flavours, fragrances, drugs Function? Maybe in interaction between plant and environment 3 groups Terpenoids, IPP as precursor, 25000 Alkaloids, amino acids as precursors, 12,000 Phenyl propanoid and polyketide, phe+acetate as precursors, 8000

  2. Poppy latex contains morphine and codeine. Dried latex yields opium. Coniine paralyzes motor nerve endings. Socrates was executed by being fed poisonous hemlock.

  3. Theriak = opium + wine + 5 plant poisons + 64 plant drug Spiders won’t eat insects that accumulate a particular alkaloid

  4. Caffeine is insecticide, inhibits PDE Hodgkin’s lymphoma Sprouting potatoes make cholinesterase inhibitor

  5. Phenylpropanoids

  6. Phe derived Polyketide derived Signalling between plant and bacteria

  7. Protects from UV-B Sensitizes to UV-A

  8. Leaf surface of thyme Spearmint glandular trichome Cross section of cavity in lemon leaf

  9. Compare plastid pathway to cytosol + ER pathway C15 and 30 in cytosol + ER, C10, 20 and 40 in plastid

  10. Essential oils
