13. photosynthesis Photosynthesis is the process by which organisms convert solar energy to chemical energy

14. History of photosynthesis

15. Leaves organization

20. What conclusion can you make from these picture?

21. How the leaves are arranged to maximize exposure to light?

22. Leaf structure

26. chloroplast

27. Stoma

28. Draw and label the cross section of the leaf

29. Chloroplast Contain green pigment called chlorophyll to absorb light

30. High density of the chloroplast in palisade mesophyll.

34. Stomata and guard cell

44. the mechanism of photosynthesis Photosynthesis occurs in chloroplast Two stages: light reaction – need light – in grana dark reaction – happen in light or dark – in stroma

46. water hydrogen ion + hydroxide ion chlorophyll chlorphyll + electron

47. hydrogen ion + electron hydrogen atom hydroxide - electron water + oxygen

48. water H + OH + - chlorophyll H [atom] e chlorophyll + e H O + O 2 2

50. carbon fixation in the stroma sugar ( CHO) + H O H atom + CO 2 2

51. photosynthesis reaction: carbon dioxyde + water glucose + oxygen

53. Discuss the differences light reaction and dark reaction:

54. Design an experiment!

55. Factors Affecting Photosynthesis Light intensity Concentration of carbon dioxide Temperature
