Transpiration- process by which plants lose water through the leaves
99% water taken into roots are transpired out the leaves 2. Water through cortex of root to xylem & up stem 1. Water from soil into root hairs 3. Transpiration in leaves helps draw water up stem 4. Water moves up stem to veins to cells Transpiration film LINK

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.
