Presentation Transcript

  1. Bellwarm up Draw a plant Write 4 things you know about plants

  2. Plant system lab

  3. Station 1 A- Chloroplast

  4. Station 1B Exposure to sunlight is reduced in the winter During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves

  5. Station 2- Tropism • Geotropism • Phototropism • Thigmotropism -vine climbing thigmotropism

  6. Station 3- Stomata • In plants, a specialized cell on the undersurface of leaves for controlling gas exchange and water loss. Guard cells occur in pairs • During warm weather, when a plant is in danger of losing excessive water, the guard cells close, cutting down evaporation from the interior of the leaf

  7. Station 4- Veins Pipelines: Xylem and Phloem • Xylem transports water • Phloem transports nutrients/ food

  8. Station 5: Celery osmosis Red dots represents xylem

  9. Arrangement of vascular bundles in the roots and stems Monocot roots: Vascular bundles are in a ring. Monocot stems: Vascular bundles are scattered.

  10. Monocot leaves have parallel venation. corn grass orchid

  11. Dicot stems – Vascular bundles arranged in a ring Dicot roots – xylem in the center of the root and phloem outside the xylem.

  12. Leaf Venation (arrangement of veins in the leaf)

  13. Monocot Dicot

  14. Analysis Discovered fossil has parallel vein arrangement in leaves: • Vascular bundle in root arranged in ______ RING (inner) B. Vascular bundle arranged in stem: _________ SCATTERED (like chocolate chipped cookies) • Is plant a monocot or dicot : ____________ MONOCOT

  15. output You came across these words in this lab: Chloroplast stomata Phototropism vascular bundles Thigmotropism sunlight Geotropism Guard cells Xylem Phloem Roots Stems Leaves Venation/veins Draw a tree and illustrate 6of these words in the diagram
