R: They are needed for CO2 reduction and RuBP regeneration.
A: Light harvesting complexes (LHC) on the thylakoid membrane broaden the range of light absorption.
R: They transfer an electron to the reaction centre.
A: For every CO2 molecule entering the C3 cycle, three ATP molecules and two NADPH are required.
R: Cyclic photophosphorylation takes place to meet the difference in the number of ATP.
A: Carotenoids protect plants from excessive heat and prevent photooxidation of chlorophyll.
R: Carotenoids enable a wider range of wavelength of incoming light to be utilised for photosynthesis.
