Cyclic photophosphorylation occurs when only light of wavelengths _______ are available.
(i) Below 680 nm (ii) Beyond 680 nm
(iii) 400 nm and below (iv) Beyond 400 nm

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

the condition(s) under which cyclic photophosphorylation occurs is/are a. light of wavelength beyond 680 nm b. anaerobic conditions c. poor CO_2 availability

the condition(s) under which cyclic photophosphorylation occurs is/are a. light of wavelength beyond 680 nm b. anaerobic conditions c. poor CO_2 availability

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.

The wavelength of light absorbed by Pr form of phytochrome is (A) 680 nm (B) 720 nm (C) 620nm (D) 640nm

The wavelength of light absorbed by Pr form of phytochrome is (a) 620 nm (b) 640 nm (c) 680 nm (d) 720 nm

Choose the correct alternative. The wavelength of ________is between 400 nm and 800 nm.
