Given below is a diagrammatic representation of the internal structure of an organelle found in a plant cell study the same and then answer the questions
(i) Identify the organelle:
(ii) Name the physiological process occurring in this organelle..
(iii) Mention one way in which this process is beneficial to man.
(iv) Name the phases of the process occurring in the part labelled '1' and ‘2’
(v) A chemical substance ‘NADP'plays an active part in one of the phases. Give the expanded from of NADP and state its role in the above process.
(vi) Represent the physiological process mentioned in (ii)) above in the form of a chemical equation..

(i) Chloroplast.
(ii) Photosynthesis.
(iii) It is a process supporting all life on earth. All animals including man, ultimately depend on plants for food as every food chains have just one starting point, i.e., plants the producers.
(iv) The process occuring in the part labelled .I is .dark, reaction or biosynthetic reaction or Calvin cycle.. The process occurring in the part labelled .II. is .light Reaction or Photochemical reaction or Hill reaction..
(v) The expanded form of NADP is Nicotinamide Adenine dinucleotide phosphate. NADP is reduced to NADPH by accepting one electron. Now this NADPH in the dark reaction transfers its hydrogen through a series of chemical reactions to combine with `CO_(2),` to produce `C_(6) H _(12) O _(6)` by using energy from ATP.
(vi) `6CO _(2) + 12 H _(2)O underset("Chloxrophyil") overset(("sun light")) to C_(6) H _(12) O _(6) + 6 H _(2) O + 6 O _(2) uarr`
