    Study Notes

    Pigments

    • Pigments are substances that absorb visible light.
    • A pigment gives color to skin, hair, and eyes, and is a colored material found in plant or animal cells.
    • Pigments absorb and reflect different wavelengths of light.
    • Plant pigments capture solar energy for photosynthesis.
    • Different pigments capture different wavelengths of light.
    • Plants need multiple pigments to capture the full solar energy spectrum.
    • Chlorophyll, carotenoids, and flavonoids are major plant pigments.

    Chlorophyll

    • Chlorophyll (a and b) is a greenish pigment in plant cells' chloroplasts.
    • Chlorophyll a is the main pigment in photosynthesis.
    • Chlorophyll a absorbs red and blue light.
    • Chlorophyll b is an accessory pigment.
    • Chlorophyll b absorbs blue and red-orange light.
    • Chlorophyll absorbs light to begin the process of converting solar energy to chemical energy.

    Carotenoids

    • Carotenoids absorb violet to greenish-blue light.
    • They dissipate excess energy as heat, which protects the photosynthetic apparatus.

    Flavonoids

    • Flavonoids produce red, yellow, blue, and purple colors.
    • Anthocyanins are a common flavonoid.
    • Anthocyanins create the red colors in many fruits, vegetables, and flowers.

    Phycobilins

    • Phycobilins are water-soluble pigments.
    • They are found in cyanobacteria and red algae.
    • They capture light energy in wavelengths where chlorophylls are less efficient,.
