Plants2 plant parts leaves; photosynthesis, stomata respiration & transpiration, includes labs, visuals, & video clips

  1. 1. Plants 2d: Plant Parts PPt. by, Robin D. Seamon LEAVES & Photosynthesis
  2. 2. LEAVES:
  3. 3. <ul><li>LEAVES: </li></ul><ul><li>Activity </li></ul><ul><li>Leaf Hunt Lab </li></ul><ul><li>Leaf rubbings </li></ul><ul><li>Leaf pressing </li></ul><ul><li>Leaf pounding </li></ul>
  4. 4. <ul><li>PARTS OF A LEAF </li></ul><ul><li>Veins carry water & minerals to the leaf; carry the food the leaf makes away from the leaf </li></ul><ul><li>Blade the main part of the leaf </li></ul><ul><li>Petiole connects the leaf to the branch </li></ul>
  5. 5. Vein Vein
  6. 6. <ul><li>KINDS OF LEAVES: </li></ul><ul><li>Simple leaves : one leaf blade </li></ul><ul><li>Compound leaves : several symmetrical leaves </li></ul><ul><li>Turn colors in the Fall & fall off- </li></ul><ul><ul><li>deciduous tree leaves will freeze in the winter, so as a precaution, trees take in all of the chlorophyl to store in the trunk & roots until spring </li></ul></ul><ul><ul><li>Leaves without green = color! </li></ul></ul><ul><li>Needles : special kinds of leaves to conserve water </li></ul><ul><li>Make food for the plant </li></ul>ADVANCE

  9. 9. <ul><li>Transpiration- process by which plants lose water through the leaves </li></ul>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
  10. 13. <ul><li>Respiration- process by which plants lose air (carbon dioxide) through the leaves </li></ul><ul><li>Guard cells close & open the stomata as needed </li></ul>
  11. 14. <ul><li>Photosynthesis- process by which plants turn sunlight into energy (food) </li></ul>http://www.grow-a-head.com/index/index.php?option=com_content&task=view&id=24&Itemid=62 HSW: video Autotrophs vs. Heterotrophs (1 min) HSW: Photosynthesis Video 2.5 min
  12. 15. 80 Hg 200.59 Mercury Atomic number (electron/proton pairs) Atomic weight symbol Element name Electron (-) nucleus Proton (+) Neutron
  13. 16. 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

  16. 19. <ul><li>PLANT LABS: </li></ul><ul><li>Leaves: Identify & graph your collection into journal; view & draw fern spores; Answer questions in Plant Journal. </li></ul><ul><li>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. </li></ul><ul><li>Seeds: seed dissection: label 3 parts of the seed into journal; observe pine nuts in pinecones-- sketch into journal; Answer questions in Plant Journal. </li></ul><ul><li>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. </li></ul>Header:

They are fragile! </li></ul><ul><li>What kinds of leaves are in your envelope? ___________, ______________, _______________, _______________, ______________ </li></ul><ul><li>Write how many of each kinds of leaves on the lines above. </li></ul><ul><li>Sketch one of the leaves, labeling the blade, veins, midriff, & petiole </li></ul><ul><li>What are the three processes performed by the leaves for the plant. _______________, ______________, _______________ </li></ul><ul><li>What is the difference between a simple leaf and a compound leaf? _____________________________________________________________ </li></ul>Header: Leaf Bank: oak, maple, dogwood, elm, beech, redbud, sweetgum
