12: Photosynthesis and Plant Pigments

  • Page ID
  • Learning Objectives

    Content Objectives

    • Understand that colors we see are determined by reflected light and relate this to the absorption spectrum of pigments
    • See how photosynthesis converts electromagnetic energy into chemical energy
    • Know the stages where products and reactants of photosynthesis are produced or used, respectively
    • Relate the process of photosynthesis to the structure of a leaf

    Skill Objectives

    • Use thin layer chromatography (TLC) to determine which pigments are present in plant tissues
    • Determine the Rf values of pigments on a TLC strip
    • Determine the relative polarity of a pigment based on the polarity of the TLC solvent
    • Identify anatomical structures in leaves involved in photosynthesis and explain their function in this process
