Assertion. In light reaction of photosynthesis, light is required for the functioning of PS I and PS II and Production of NADPH and ATP. Reason. Dark reaction does not occur in light.

Translate the following statement into symbolic into symbolic from. (i) Rahul passed in Hindi and English. (ii) x and y are even integers. (iii) 2, 3 and 6 are factors of 12. (iv) Either x or x + 1 is an odd integer. (v) A number is either divisible by 2 or 3. (vi) Either x= 2 or x = 3 is a root of 3x^(2) - x - 10= 0 (vii) Students can take Hindi or English as an optional paper.

Splitting of water molecules during light reaction of photosynthesis is associated with (a) PS I resulting the release of O_(2) , protons and transfer of electrons to PS II (b) PS II resulting in release of O_(2) , protons and transfer of electrons to PS I (c) PS II resulting in release of O_(2) , protons and transfer of electrons to PS II (d) PS I resulting in the release of O_(2) , protons and transfer of electrons to PS I. Of the above statements

Which of the following statements with regard to photosynthesis is/are correct? I. In C3 plants, the primary CO_2 acceptor is RuBP. II. In the photosynthetic process, PS-II absorbs energy at or just below 680 nm. III. The chlorophyll-a that is present in the photosystem-I has absorption maxima at 680nm.

Which of the following statements with reagards to photosynthesis is/are correct (A) In C_(4) plants, the primary CO_(2) acceptor is PEP (B) In the photosynthesynthetic process PS II absorbs energy at or just below 680nm (C ) The pigment that is present in the pigment system I is P_(683)

The Figure shown below represents an activity to prove the requirements for photosynthesis. During this activity, two healthy potted plants were kept in the dark for 72 hours. After 72 hours, KOH is kept in the watch glass in setup X and not in setup Y. Both these setups are air tight and have been kept in light for 6 hours. Then, Iodine Test is performed with one leaf from each of the two plants X and Y. Which of the following steps can be followed for making the apparatus air tight? i. placing the plants on glass plate ii. using a suction pump. iii. applying aseline to seal the bottom of jar. iv. creating vacuum
