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.

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

Assertion: The stoma lamellae have both PS I and PS II. Reason: The grana lamellae lack PS II and well as NADP reductase enzyme.

Assertion: The stoma lamellae have both PS I and PS II. Reason: The grana lamellae lack PS II and well as NADP reductase enzyme. Photosynthesis in Higher Plants A If both assertion and reason are true and reason is the correct explanation of assertion B If both assertion and reason are true but reason is not the correct explanation of assertion C If assertion is true but reason is false D If both assertion and reason are false

Assertion : The stromal thylakoids are rich in both PS I and PS II Rason : The granal membranes are rich in ATP synthetase.

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

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

Assertion :- In Stroma lamellae cyclic photophosphorylation is the only mean of ATP synthesis Reason :- In stroma lamellae both PS-II and NADP reductase enzyme are absent.

Assertion :- Both PS-I and PS-II are located on stroma thylakoid membrane Reason :- Photolysis of water and reduction of NADP^(+) takes place in stroma site.
