1. metabolites
madison jennings

3. Plants are alive too...
semi conscious
able to release secondary metabolites
use of primary metabolites

4. Primary Metabolites
variety of uses
communication, cell repair

5. Communication
Primary metabolites are triggered by a plant cell
change
can signal for a need else where in the plant

6. Cell Repair
Signal a damaged cell
allow other cells to send new building materials
signal the destruction

7. Secondary Metabolite
Classes
several types
chemical defense, attractant, self medicating, poison
terpenoids, alkaloids, phytoalexins, phenolic

8. phytoalexins
self medicating
induced by infection or wounding
immune response in plants
often what is used in “herbal medication”

9. Alkaloids
protect the plants
“pharmacologically active”
morphine, caffeine, nicotine

10. Terpenoid
oils or fragrances (orange, peppermint)
many are highly poisonous (Cardiac glycosid)
antiherbivory, or attractants

11. phenolic
bitter tasting flavenoids
Can be lignin
pits of fruit
water retention
most common tannins
antiherbivory , toxic
caffine, tea, cinnamon

12. Supermarket Produce
crops are disarmed of metabolites
susceptible to animals and humans
these qualities are “bred out”

13. Every Day Uses
derive medication
spices
pesticides

14. medication
toxicity can be altered if diluted
different parts of the plant provide different remedies
doctrine of signatures helped to denote uses

15. spices
bitter flavenoids
rich flavors
beneficial in tea

16. pesticides
secondary metabolites
provide protection to the unarmed plants
show the toxicity of the metabolites

17. Reduction of
Competitors
limited resources
must use apical growth
or secrete poison
wipe out competition

18. Necessity
to get rid of waste
to destroy built up starches
to adapt to lack of resources

19. Summary
For survival -- pollinators, seed dispersal, self
medicating
allelopathy-- secrete poisons via the roots
accidental -- due to no excretory system
