Photosynthesis

• Structure of chloroplast

  A) Ribosome

  B) Stroma

  C) Inner membrane

  D) Intermembrane space

  E) Outer membrane

  F) Chloroplast DNA

  G) Starch granule

  H) granum

  I) lamella

  J) thylakoid

  K) Drop of lipids

  
• Light is made up of energy called protons
• Short wavelengths have high energy protons, long wavelengths have lower energy protons
• Chlorophyll is embedded in the thylakoid membrane
• Chlorophyll is made up of magnesium
• Chlorophyll absorbs sunlight energy
• Absorption spectrum

  • Rate of light absorption of different wavelengths
• Action spectrum

  • Rate of photosynthesis at different wavelengths
• Evidence suggests that the similar patterns on both the absorption spectrum and the action spectrum shows that both are used in photosynthesis
