IB Biology SL C1.3.5 Absorption of specific wavelengths
Practise explaining how chlorophyll and other pigments absorb selected wavelengths, especially red and blue light, while green is reflected.
How this is tested
- compare absorption of red, blue and green light by chlorophyll
- explain why leaves appear green using reflection and absorption of light
- predict colours absorbed efficiently by pigments from their observed colour or role
