Presentation Transcript

  1. Unit: Plant Biology Advanced Plant Sciences Mr. Dieckhoff

  2. Chapter 1 Plant Cells

  3. 1. ID the parts of a plant cell… • Chloroplast – holds chlorophyll • Plasma Membrane – Controls entrance & exits • Cell Wall – 3 layers • Vacuole – Store water • Mitochondrion – Respiration • Nucleus - Genetics

  4. Plant Cell Video https://www.youtube.com/watch?v=9UvlqAVCoqY

  5. Cell Wall Structure

  6. Too little water in vacuole…..

  7. Tobacco flower losing pigment because lack of mitochondria proteins

  8. How Roundup Works on Plant Cells… • https://www.youtube.com/watch?v=qZeMJ-OovGs

  9. Chapter 2 Plant Tissue

  10. 5. What are 2 types tissue…. • Meristem • Permanent

  11. 6. What are differences…… Meristem actively divides to form new growth where permanent does not actively divide

  12. 7. What are 3 types meristems.. • Apical – plant length • Cambium – plant diameter • Intercalary Zone – stem height

  13. **Cambium Meristem

  14. Intercalary Zone Meristem

  15. 8. What two types permanent… • Epidermis – outside covering 2) Vascular System – transportation system of plant • Xylem - Up • Phloem - Down

  16. **Five basic parts of a plant: A. Seeds • B. Roots • C. Stems • D. Leaves • E. Flowers

  17. Chapter 3 Seeds & Germination

  18. Monocots vs. Dicots • https://www.youtube.com/watch?v=gI2RxzAT-ww

  19. Cotyledon • First leaves packed full of nutrients

  20. Parts of a Monocot Seed

  21. Parts of a Dicot Seed

  22. Which is found only in monocots Endosperm

  23. 4 parts of the embryo • Cotyledon • Epicotyl – “stem” • Hypocotyl – “growing point” • Radicle – “root”

  24. Legumes • Dicot plants with pods that fix their own nitrogen

  25. Steps of Germination • Seed absorbs water • Seed coat breaks open • Radicle Emerges & forms roots • Epicotyl breaks through soil • Cotyledon(s) open • Leaves form & photosynthesis starts

  26. Chapter 4 Roots

  27. Don’t cut alfalfa in October

  28. Wait Until November

  29. Or Next Year will Look Like….

  30. 15. What are 5 types roots…. • Taproot • Fibrous • Aerial • Adventitious • Aquatic

  31. Adventitious Roots

  32. Tap Root

  33. Aerial Roots

  34. Aquatic Roots

  35. Nitrogen Fixation in Soybeans • https://www.youtube.com/watch?v=Ui6JlVGmAuA&t=1s&disable_polymer=true

  36. Chapter 5 Stems

  37. Stems are divided into….

  38. Purpose of Stems • Support • Transport nutrients & food • Store some nutrients

  39. Stolon
