Poison Ivy
Poison ivy produces urushiol—an oily chemical that discourages herbivory and produces a nasty rash when people contact it.
Holly
leaves of holly plants are coated with waxes and resins (thick liquids that
harden into transparent solids) that make them slippery and difficult for
animals to eat
DandelionThe dandelion plant secretes latex (a milky sap) when its leaves are broken
which causes insect mouth parts to become very sticky.
Stinging Nettle
leaves and stem are covered with trichomes- hairs on the leaves with
hypodermic needles containing histamine—a chemical that produces a
stinging sensation
C. Thigmonasty occurs when plants
move their parts to avoid herbivory
