Practise IB Biology HL 8.3.5 by analysing absorption spectra, pigment diversity and wavelength selection in autotrophic light capture.
Distinguish between the absorption of red light, blue light and green light by plants.
chlorophyll is the main photosynthetic pigment;
b. high levels of absorption in red light and blue light; (both needed)
c. greatest absorption in blue light;
d. least/low absorption in green light;
e. green light is reflected;
f. other pigments absorb other wavelengths/colours;
Marking guidance:
Allow graph showing the absorption.
