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,.
