Practise comparing pigment absorption spectra with photosynthetic action spectra, sketching wavelength graphs and explaining why green leaves use blue and red light most…
Explain the relationship between the action spectrum and the absorption spectrum in photosynthetic plants.
action spectrum is quantity of photosynthesis for each wavelength; absorption spectrum is quantity of light absorbed (by a pigment) for each wavelength; absorption spectra of each pigment add up/correlate to make action spectrum / OWTTE;
