  • 1. Classification & Processes

2. PLANTS: How are plants divided up? How are they related? How are they different? Nomenclature:(naming of species) 3. PLANTS Nonvascular Vascular Mosses Lichens NOT A PLANT: Fungi/ mushrooms SEEDS NO-SEEDS Angiosperms Gymnosperms Monocots Dicots Conifers NO-SEEDS Ferns Horsetails 4.

  • Nonvascular plants(lacking vessels), short & delicate
  • Mosses
  • 1. cling to damp soil, rocks, shady trees
  • 2. are tiny plants (1-2 inches tall)
  • 3. leaves are only 1-2 cells thick
  • 4. anchored withrhizoids(hair-like fibers)-not roots.
  • 5. seedless; grow fromspores
  • a)lichens : grow on tree; looks like scales/shells
  • b)fungi/mushrooms : grow on the ground

  • II.Vascular: having vessels, divided into Seedless & seeds

SEEDLESS SEEDS Vascular 8. B.SEEDLESS : do not have seeds;use spores to reproduce, grow tall & thick EXAMPLE:fern http://www.freefoto.com/images/9909/06/9909_06_6179---Fern_web.jpg?&k=Fern http://www.shadegarden.net/wp-content/uploads/2008/07/cinnamon-fern.jpg http://eatdrinkbetter.com/2008/05/05/lovin-fresh-fiddlehead-ferns/ 9. SEEDS: GYMNOSPERMS ANGIOSPERMS Gymnosperms(naked seed); noflowers; oldest kind of seed plants,they like cold/dry climates,use sexual reproduction,produce seeds on female cones http://www.netstate.com/states/symb/flowers/images/pine_cone_tassel.jpg 10. Conifer http://www.bentler.us/eastern-washington/plants/trees/ponderosa.aspx http://www.panzhihua-university.com/pictures/cycads.jpg Cycad http://www.gardenexpress.com.au/images/P/Cycad-01.jpg 11.

  • Angiosperms(flowering) produceflowers, form the largests division in plantkingdom; live lots of places/climates
    • form seeds inside their fruits
    • Use sexual reproduction/pollination
    • Examples: fruits, vegetables, grains, most nuts
    • Have a seed leaf or COTYLEDONS (2 kinds)

Angiosperms MONOCOTS DICOTS 12.

  • Monocotshave one cotyledon, (corn, rice, wheat, grasses)
  • Dicotshave 2 cotyledons (bean plant, roses, cacti)

  • Parts of a plant:What are they for?
  • Seeds
  • Roots
  • Stem
  • Leaves
  • Flowers
  • Makes more of the plant (babies)
  • Takes in water, anchors it, stops erosion
  • Holds up plant, water up & down
  • Makes food for the plant, breathes
  • Attracts a pollinator to make a seed

15. 16. Plant Life cycle 17. What do plants need to survive? water Air(carbon dioxide) Soil (minerals) sunlight 18.

  • Important processes:
  • Germinationprocess by which a seed sprouts
  • Pollinationprocess of spreading pollen to fertilize a flowers egg to make a seed
  • Transpirationleaves releasing water into the air
  • Respiration leaves releasing oxygen
  • Photosynthesisplants turn sunlight into food

Suns energy splits water molecule into hydrogen & oxygen 3. Hydrogen joinscarbon dioxide tomake food(sugar/glucose) 4.

  • Leaves:Identify & graph your collection into journal; view & draw fern spores; Answer questions in Plant Journal.
  • Flowers:identify & draw 5 local spring flowers on white paper.Glue into journal. Roots:identify fibrous & taproots; draw 7 label root parts in journal;Answer questions in Plant Journal.
  • Seeds:seed dissection:label 3 parts of the seed into journal; observe pine nuts in pinecones-- sketch into journal;Answer questions in Plant Journal.
  • Stems:Compare three different types of bark.Notice the color & texture.How do the grains run?Is there a pattern?Create a bark rubbing with a dark crayon (rubbed sideways).Sketch the three specimens.
