  1. Bio 369: Plant Physiology William Terzaghi Spring 2013

  2. COURSE OVERVIEW • 1) Understanding how plants work.

  3. Understanding how plants work. • Solar input = 1.3 kW/m2

  4. Understanding how plants work. • Solar input = 1.3 kW/m2 • 5% (max) can be stored in organics

  5. Understanding how plants work. • Solar input = 1.3 kW/m2 • 5% (65W/m2) can be stored • Humans consume ~ 100 W (360,000 J/hour)

  6. Understanding how plants work. • Solar input = 1.3 kW/m2 • 5% (65W/m2) can be stored • Humans consume ~ 100 W (360,000 J/hour) • Plants must have high surface area & low metabolism

  44. Plant Structure • 3 Parts • Leaf • Stem • Root

  45. Plant Structure • 3 Parts • Leaf • Cuticle = lipid barrier

  46. Plant Structure • 3 Parts • Leaf • Cuticle = lipid barrier • Epidermis = barrier cells

  47. Leaf Structure Cuticle = lipid barrier Epidermis = barrier cells Stomate = gate controlled by guard cells

  48. Leaf Structure Cuticle = lipid barrier Epidermis = barrier cells Stomate = gate controlled by guard cells Mesophyll = photosynthetic cells

  49. Leaf Structure Cuticle = lipid barrier Epidermis = barrier cells Stomate = gate controlled by guard cells Mesophyll = photosynthetic cells Bundle Sheath = control import/export

  50. Leaf Structure • Bundle Sheath = control import/export • Vascular tissue = plumbing • Xylem = water & inorganics • Dead!
