Cyclic photophosphorylation occurs under which condition?

Which process also occurs when only light of wavelengths beyond 680 nm are available for excitation?

Assertion: Stroma lamellae have both PS I and PS II but the membrane of grana lack PS II as well as NADP reductase. Reason: Cyclic photophosphorylation also occurs when only light of wavelength below 680 nm is available for excitation.

(c) How many photons per second does a one watt bulb emit if its efficiency is 10% and the wavelength of light emitted is 500 nm? (d) Monochromatic light of wavelength 300 nm is incident normally on a surface of area 4 cm^(2) . If the intensity of light is 150 m W//m^(2) , determine the rate at which photons strike the surface.
