Photosynthesis In Higher Plants(12th Grade > Biology ) Questions and Answers
Explanation:-
Answer: Option A. -> It is a characteristic of C4 plants:
A
DickerandTio(1959) discovered photorespiration in tobacco plant. It is a light dependant process of oxygenation of ribulose biphosphate (RuBP). During this process, carbon dioxide is liberated and oxygen is consumed. C4 – plants avoid photorespiration by following Hatch-Slack pathway.
Explanation:-
Answer: Option D. -> Photolysis of water and phosphorylation of ADP to ATP:
D
Photochemical reaction is also known as light reaction because it takes place in the presence of light in the grana portion of chloroplast. In this reaction, photolysis of water takes place, which generates oxygen simultaneously; photophosphorylation takes place which generates ATP and NADPH.
Explanation:-
Answer: Option C. -> Assertion is true but the reason is false.:
C
In the case of cyclic phosphorylation, the electron, while passing between ferredoxin and plastoquinone and or over the cytochrome complex the electron loses sufficient energy to form ATP from ADP and inorganic phosphate However, is not donated to NADP+.
