Photosynthesis Assertion and Reason
These Photosynthesis Assertion and Reason questions consist of two statements each, printed as “Assertion” and “Reason“. While answering these Questions you are required to choose any one of the following responses.
(1) If both A and R are True and the R is a correct explanation of the A.
(2) If both A and R are True but R is not correct explanation of the A
(3) If A is True but the R is False.
(4) If both A and R are false.
A : Evolution of O2 is not linked with bacterial photosynthesis.
R : Bacteria absorb the I-R spectrum.
A : Utricularia captures insects for nitrogen source.
R : This plant grows in nitrogen deficient habitats.
A : One mole of oxygen gas liberates in bacterial non cyclic ETS.
R : Bacteria is first photosynthetic Eukaryotes.
A : Lysosomes help in the process of photorespiration.
R : Lysosomes have enzymes for photorespiration.
A : O2 is not released in photosynthesis of bacteria.
R : Photolysis of water is absent in bacterial photosynthesis.
A : Action spectrum of photosynthesis is Red & Blue colours of light.
R : Plants absorb maximum Red and Blue colour.
A : D.C.M.U. is a photosynthetic inhibitor.
R : D.C.M.U. inhibits photolysis of water.
A : For evolution of O2 in photosynthesis, PS-II is required.
R : O2 is released in photosynthesis, of Chromatium.
A : Photorespiration is a wasteful phenomenon in C3-plants.
R : Decrease in photosynthetic productivity due to photorespiration.
A : Dark reaction does not occur in absence of light.
R : Synthesis of assimilatory powers occurs during light reaction.
