  1. Wednesday 3/6

  2. Agenda 3/6 • Plant Station Lab • You will need your computer or paper

  3. Objective 3/6 • Objective: Examine specialized cells, including roots, stems, and leaves of plants (5B) • Students will examine specialized cells within roots, stems and leaves using equipment such as microscopes/microslides / or observations of organism or images. • Student should be able to describe the importance of these specialized cells to the plant.

  4. Plant Structure and Function • Sketch or write about information in the video: http://www.youtube.com/watch?v=fVfV5LMXh2s

  5. Station 1: Cells of a Leaf • Draw/Sketch a picture of a leaf cell: • What are the parts or features of the plant leaf in photosynthesis? • What is the importance of stomata?

  6. Station 2:Cells of the Stem • Draw/Sketch a picture of the cells of a stem: • What is the importance of the meristematic tissue? • Predict what would happen to the plant if the meristematic tissue was damaged.

  7. Station 3: Cells of the Root • Draw/Sketch a picture of a root cell: • What is the function of xylem and phloem in a plant? • Give an analogy of something that has a similar function to xylem and phloem:

  8. Station 4: Cells of a Flower • Draw/Sketch a picture of a flower including its reproductive parts: • Angiosperms evolved after gymnosperms. Why might angiosperms be better at reproducing and therefore dominating the planet?

  9. Bonus Stations 5-8 • List the 4 classes of plants • Give a brief description of the 4 classes of plants

  10. Conclusion Questions • What could be done to maximize photosynthesis? • What would happen if all the leaves on the plant fell off? • Can you predict the outcome if the xylem or phloem got blocked?

  11. Extend your thinking… • Can you construct a model that would change the way plants receive nutrients if sunlight, water, and carbon dioxide wasn’t readily available?
