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

5. Cell Wall Structure

9. Too little water in vacuole…..

11. Tobacco flower losing pigment because lack of mitochondria proteins

13. How Roundup Works on Plant Cells…

14. Chapter 2
Plant Tissue

15. 5. What are 2 types tissue….
Meristem
Permanent

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

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

20. **Cambium Meristem

21. Intercalary Zone Meristem

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

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

25. Chapter 3
Seeds & Germination

26. Monocots vs. Dicots

27. Cotyledon
First leaves packed full of nutrients

28. Parts of a Monocot Seed

29. Parts of a Dicot Seed

30. Which is found only in monocots
Endosperm

31. 4 parts of the embryo Cotyledon Epicotyl – “stem”
Hypocotyl – “growing point”
Radicle – “root”

32. Legumes
Dicot plants with pods that fix their own nitrogen

33. 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

34. Chapter 4
Roots

36. Don’t cut alfalfa in October

37. Wait Until November

Store some nutrients

50. Stolon

51. Rhizomes

52. Corm

53. Bulb

54. Tubers

55. Xeromorphic Plants
Thick-walled epidermis covered with waxy cuticle (holds water in stems)

56. Chapter 6
Leaves

57. Interior Parts of Leaf

58. View Guard Cells & Stomata of Wandering Jew

59. 20. What do not have stomata?
Submerged plants (aquatic)

60. Sac leaves

61. Leaf Arrangements Simple Leaf – one blade attached to the stem
Compound Leaf – multiple leaves attached to stem through petiole
Palmate – Leaves come together like a palm
Pinnately – leaves separated by divisions

62. Chapter 7
