    • - half of plants are winter-forests, half are tropical
    • -Branches:laterally
  12. Temperate: Height
    35m

    Spreading
  14. Temperate: Fire Resistant
    No
  15. Temperate: Roots
    Lateral
  16. Tropical
    • -limiting factor of light

  21. Gymosperms
    • -oldest, 1st to exist
    • -sperm means "seed"
    • -gym means "naked"
    • -NOT FRUITS
    • -Pollination: wind carries pollination
  22. Angiosperms
    • "box seed"
    • -has ovary that will create fruit
    • -newer than gymnosperm plants
    • -Pollination: Insects carry pollen
  23. Dicots
    • -netted veins,
    • -
    • floral formulas (parts) in sets of 4 or 5
  24. Monocots
    • -Paralleled Veins, flower parts in multiples of 3
    • -Ex. grasses, lilies, palm trees, orchids, irises
  25. Wood Rings
    • -shows the age of trees and their growing seasons
    • -tropical trees never stop growing, so no rings
    • -Warm- big rings.
    • -Cold- small rings.
    • -Tropics- no rings.
    • -Boreal-always has ring

    • 2. Pistil: Female reproductive part of angiosperms
  34. Dioecious
    • there are males/females,like human (gingko)
