IB Biology C1.3.6 Absorption vs. action spectra
Practise reading absorption and action spectra to connect wavelength, pigment absorption and relative photosynthesis in plants and algae.
How this is tested
- interpret action spectra as relative photosynthesis at different wavelengths
- compare absorption spectra with action spectra to infer useful light colours
- deduce habitat depth or oxygen release from photosynthesis under different light colours
