1. Select the correct statement about
photophosphorylation :
(1) Cyclic photophosphorylation involves photolysis
of water
(2) Cyclic photophosphorylation always occurs in
granal thylakoid
(3) External electron donor is required in cyclic
photophosphorylation
(4) Only PS-I is involved in cyclic
photophosphorylation
2. Select the incorrect statement about CO2 in
photosynthesis :
(1) Rate of photosynthesis decreases with increase
in CO2 concentration above 0.05%
(2) Green house crops (C3 plants) show CO2
fertilization effect
(3) Atmospheric CO2 is rarely a limiting factor for
C3 plants
(4) High concentration of CO2 in C3 plants causes
photorespiration
3. Read the following statements :
(i) PS-I and PS-II were numbered I and II
according to the sequence in which they function
during light reaction
(ii) The LHC are made of hundreds of pigment
molecules bound to the proteins
(iii) Many chlorophyll-a molecules form one
reaction center
(iv) The reaction center is different in PS-I and
PS-II but with the same absorption peak of
wavelength of light.
(v) In PS-II, the reaction center chlorophyll-a
gives out 685 nm wavelength of red light causing
electrons to become excited and jump into an
orbit farther from the atomic nucleus Which of
the above statements are correct ?
(1) (i), (ii) and (iii)
(2) (v) only
