II. Vascular: “having vessels”, divided into Seedless & seeds
SEEDLESS SEEDS Vascular
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/
SEEDS: GYMNOSPERMS ANGIOSPERMS Gymnosperms (naked seed); no flowers; 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
Pollination process of spreading pollen to fertilize a flower’s egg to make a seed
Transpiration leaves releasing water into the air
Respiration leaves releasing oxygen
Photosynthesis plants turn sunlight into food

1. Chlorophyll absorbs light from the sun 2. Sun’s energy splits water molecule into hydrogen & oxygen 3. Hydrogen joins carbon dioxide to make food (sugar/glucose) 4. Sugar carried through the plant; oxygen is released into the air 6 6 6 PHOTOSYNTHESIS H 2 O O 2 CO 2 = + + C 6 H 12 O 6 MOVE
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.
