A: Dark acidification occurs in CAM plants.
R: Organic acids are decarboxylated during the night.
A: Assimilatory power in photosynthesis is generated in ETS occurring in the thylakoid membrane.
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.
A: Biosynthetic phase of photosynthesis depends directly on the presence of light.
R: Both ATP and NADPH are not essential for the assimilation of CO2 to carbohydrates.
A: Most of the photosynthesis takes place in the blue and red region of the spectrum.
R: Action spectrum shows the amount of energy of different wavelength of light absorbed by pigments.
A: Tropical plants are more efficient in CO2 utilization.
R: C3 plants ensure that RuBisCO functions as carboxylase minimising oxygenase activity.
