  1. Tree Identification AG-FS-4. Students will identify trees and explain their environmental and economic value. c. Explain the differences between Angiosperms and Gymnosperms. d. Identify and classify common tree species. e. Identify the economic and environmental value of common tree species.

  2. Explain the differences between Angiosperms and Gymnosperms. • Trees are members of the plant kingdom • Divided into: • Classes- Angiospermae (Hardwoods) or Gymnospermae (Conifers) • Orders- end in ales • Families- end in aceae • The scientific name is Genus and species • Ex. Acer rubrum- red maple

  3. Identify and classify common tree species. • Most important characteristics in the identification of trees are • Leaves • Twigs • Bark • Reproductive structures • Fruit in angiosperms • Cones in gymnosperms

  4. Leaves- Most trees identified by type, size, shape color, texture and arrangement of leaves • Apex- tip • Margin- edge of leaf • Primary vein- main vein • Blade- flat, expanded part of leaf • Secondary veins- veins branching off from primary vein • Base-are of leaf that attaches to petiole or stem • Petiole- stalk of leaf that attaches to stem • Stem- part of tree that develops buds and shoots • Axillary bud- bud located in axil of leaf • Stipules- basal appendages of leaf

  5. Leaf Types Simple- only one blade per leaf Compound- Three or more leaflets per leaf Double-pinnately compound Palmately compound Pinnately compound

  6. Leaf Arrangements Opposite- leaves are paired at the same node Alternate- only one leaf per node Whorled- more than two leaves grow from the same node
