6. Seed germination of a plant is influenced by only intrinsic factors.

7. When proton carrier molecule passes on its electron to the electron carrier on the inner side of the membrane, the proton is released into the inner side or the lumen side of the membrane.

8. Phosphoenolpyruvate – 6C compound.

9. Fumarate → malonate, does not couple with the GTP production.

10. Formation of meristems – interfascicular cambium and cork cambium from fully differentiated parenchyma cells is redifferentiation.

13. Gibberellins also promotes internode elongation just prior to flowering in beet.

14. Almost all living cells in a plant have their surfaces not be exposed to oxygen.

15. Pyruvic acid – 6C compound.

16. General principles for differentiation for cell, tissues and organs are similar.

17. Respiration refers to the breaking of the C–C bonds of complex compounds through oxidation inside the cells, leading to the release of considerable energy.

18. Root and shoot apical meristems always along with lateral meristem, contribute to the elongation growth of plant axes.

19. In photosynthesis, the proton accumulation is towards the inside of the membrane.

20. In glycolysis, Glucose 6 phosphate is converted to fructose 6 phosphate which is coupled with ATP utilisation.

21. Cytokinins promote nutrient mobilisation which helps in the delay of leaf senescence.

22. The living differentiated plant cells, that by now have lost the capacity to divide cannot regain the capacity of division under certain conditions.

23. Gibberellins can be isolated from fungi.

24. In glycolysis, Dihydroxy acetone phosphate is converted to 1,3 bisphosphoglyceric acid which is coupled with NADH utilisation.

25. The breaking of C-C bonds of complex organic molecules by reduction in cells leading to the release of a lot of energy is called cellular respiration.

26. In glycolysis, Fructose 6 phosphate is converted to fructose 1, 6 bisphosphate which is do not coupled with ATP production.

27. Cytokinins helps to produce new leaves, chloroplasts in leaves, lateral shoot growth and adventitious shoot formation.

28. Proteins are oxidised to release energy.

29. The breakdown of complex molecules to yield energy takes place in the mitochondria but not in the cytoplasm.

30. When 2 phosphoglyceric acid changes into phosphoenolpyruvate in glycolysis, the step is coupled with ATP utilisation.

31. Protein is not the favoured substrate for respiration.

32. Fumarate → malonate, coupled with the FADH₂ production.

33. The primary CO₂ fixation product in C₃ plants is OAA.

34. Citric acid → isocitric acid, does not couple with the O₂ release.

35. NADH + H⁺ and FADH₂ are generated in the Krebs’ cycle.

36. Along with electrons that come from the acceptor of electrons of PS II, protons are necessary for the reduction of NADP+ to NADPH+ H+.
