  1. Monday, Nov. 18 Video clip Book activity: Intro to photosynthesis Explain sub activity for tomorrow

  2. Cycles in everyday life Water Carbon Life Nitrogen Food Light/energy

  3. Text book • Page 226-228 • Questions 1-2 • Page 230-234 • Questions 1 & 3a

  4. Wednesday, Nov. 20 Photosynthesis 8.1/8.2 Notes Introduce gizmos Gizmo lab

  5. Energy and Life • Energy is the ability to do work • Forms: light, heat, and electricity. Can be stored in chemical compounds. • ATP= adenosine triphosphate • Basic energy source for all cells • ADP= adenosine diphosphate • Only two phosphate groups, stores energy

  6. Uses Active transport (protein pumps) Synthesis of proteins Responses to chemical signals

  7. Heterotrophs and Autotrophs • Heterotrophs- obtain food by consuming other living things • Autotrophs- obtain food by making their own. • Photosynthesis- convert light energy into chemical energy

  8. Chlorophyll • Pigments- light-absorbing molecules • Chlorophyll- pigment in plant • Absorb light in the blue-violet and red regions • Reflect green light- that’s why they look green

  9. Chloroplasts Chloroplasts- place where photosynthesis takes place Thylakoids- saclike membrane, inside chloroplasts, arranged in stacks= grana

  10. Electrons Light energy absorbed by chlorophyll, transferred to electrons

  11. Overview of photosynthesis Reaction: 6CO2 + 6H2O C6H12O6 + 6O2 Carbon dioxide plus water, light- yields sugar and oxygen

  12. Light-dependent reaction • First set of reactions- require direct involvement of light and light-absorbing pigments • Uses energy from the sun to produce ATP • Takes place in the thylakoid • Water required as source of electrons and H ions. Oxygen released as byproduct

  13. Light-independent reaction • ATP and NADPH molecules produced in the light reaction are used to produce sugars from CO2 absorbed from the atmosphere • Takes place in the stroma, liquid outside the thylakoid

  14. Thursday, Nov. 21 Review gizmos Leaf structure/function Stomata lab

  15. Leaf Anatomy Location of Photosynthesis Veins- phloem and xylem Guard cells- allow CO2 in, O2 out.

  16. Quick video leaf structure
