10. Cell Walls

11. Water transport thru cells

14. Cellular Development: Mitosis

15. Early Cellular Development: The seed

30. The Generic Seedling

36. Tropical Rain Forest Moist, high temps Consistent year round growth High diversity Some adaptations: –Most plants evergreen –Drip tips –Epiphytes –Waxy leaves

37. Southeastern mixed forest Nutrient poor and seasonally flooded soils Still warm temps, but lower humidity Both deciduous and evergreen Fire adapted

38. Temperate Deciduous Forest Too cold/dry in winter to support much photosynthesis Snow melt allows for rapid growth in spring Very similar to species found in Asia

39. Taiga Limited by temperature Acidic soils Mostly evergreen trees

40. Grasslands Temperature extremes, too dry and too much fire to support forest Few trees, mostly grasses and forbs C3 and C4 grasses: dominance determined by temp and water Very little original prairie left

41. Hot Desert Hot, dry Mostly cacti, shrubs, grasses Slow growing vegetation Adaptations: –Water stress –CAM photosynthesis –Protection against herbivory

42. West Coast biomes

43. Communities: Groups of interacting organisms in a given place

44. Which organisms do plants interact with? Positive interactions: –Pollinators –Seed dispersers –Nitrogen fixing bacteria and fungi –Animals that prey upon herbivores Negative Interactions –Herbivores –Fungi –Pathogens

45. Lab: How are plants adapted to their particular environments? What adaptive trait do you see? How is this an adaptation to this plant’s environment?
